I. Current/Voltage Output DACs: Core general-purpose analogue output components, suitable for diverse industrial scenarios

Current output DACs and voltage output DACs are ADI’s most fundamental and widely used general-purpose digital-to-analogue converters. They are characterised by high flexibility, high compatibility and high energy efficiency, primarily enabling the precise conversion of digital signals into standard analogue current/voltage signals. They serve as core components in industrial control, power regulation, optoelectronic systems and general-purpose signal output applications. These two product categories are designed to cater to different load requirements, covering the vast majority of standard analogue output applications.

1. Voltage-Output DACs

ADI’s voltage-output DACs utilise the two mainstream architectures—resistor-stacked and R-2R—and feature a comprehensive product portfolio covering a wide range of specifications, from single-channel to multi-channel, single-supply/dual-supply, and unipolar/bipolar outputs, meeting the requirements for low-voltage, high-precision and low-power voltage output. The core advantages of this product series include high output voltage linearity, stable settling time and minimal offset error. They can output standard voltage signals without the need for additional operational amplifier circuits, thereby simplifying system design and reducing overall system cost and size.

The products support multi-channel, high-density integration, with a single chip capable of delivering up to 40 channels of synchronous output, making them ideally suited for multi-channel analogue control applications. They also feature a low-voltage operating mode, making them suitable for battery-powered and low-voltage industrial control equipment, whilst offering excellent low-temperature drift characteristics and stable output accuracy across a wide operating temperature range.

Typical applications: industrial PLC analogue output modules, sensor calibration, reference voltage sources, smart control of domestic appliances, low-voltage servo control systems, and portable instruments and meters.

2. Current-Output DACs

ADI’s current-output DACs are specifically designed for applications requiring low current noise, low dropout voltage, high energy efficiency and high current output. Unlike voltage-output products, they offer superior load-driving capability; certain high-end models can achieve a maximum programmable current output of 300 mA and support flexible configuration of current-source modes, making them suitable for high-load, high-precision current control applications. This product series features extremely low current noise density, exceptional output current stability and outstanding immunity to interference, effectively suppressing the impact of electromagnetic interference on analogue signals.

It also offers excellent low-dropout operating characteristics, enabling stable operation without the need for significant voltage drop headroom, which significantly reduces system power consumption and makes it suitable for industrial and optoelectronic equipment requiring long-term continuous operation.

Typical applications: laser and optoelectronic control, precision LED dimming, industrial current drive modules, solenoid valve control, high-end lighting systems, and precision current source equipment.

II. Direct Digital Synthesis (DDS) (DAC-integrated architecture): Programmable high-precision signal generators

DDS (Direct Digital Synthesis) is a distinctive, specialised DAC product from ADI. Unlike general-purpose DACs, it is a fully integrated digital frequency synthesis chip that combines a DAC, frequency and phase registers, a clock module and a comparator. It enables the precise generation of arbitrary waveform signals—such as sine, square and triangular waves—via digital programming without the need for complex peripheral circuitry, providing a minimalist and highly flexible signal generation solution.

The core advantages of ADI’s DDS product series are ultra-low power consumption, ultra-high frequency resolution, rapid frequency switching and programmable modulation. The products feature built-in independent frequency, phase and amplitude registers, and support rapid programming via a three-wire serial interface, enabling precise frequency, phase and amplitude modulation. The frequency switching process occurs without phase jumps, ensuring excellent signal integrity.

Represented by the classic AD9834 model, this device supports signal synthesis up to 50 MHz and features an on-chip comparator capable of directly outputting standard clock signals without the need for additional shaping circuits, thereby significantly simplifying the signal generation system architecture. Some high-end DDS products support multi-waveform superposition and frequency-sweep output, catering to complex dynamic signal generation requirements. Compared to traditional phase-locked loop (PLL) and crystal oscillator signal solutions, ADI DDS offers the advantages of higher resolution, greater flexibility in control, smaller form factor and lower power consumption.

Typical applications: local oscillator sources for communication systems, signal generators for instruments and meters, radar frequency modulation systems, medical and physiotherapy signal equipment, clock synchronisation systems, and IoT RF signal modulation.

III. High-Speed DACs: Ultra-wideband RF signal conversion, enabling high-frequency communication scenarios

ADI’s high-speed DACs are specifically designed for ultra-high-speed sampling, ultra-wideband signal synthesis, and RF/microwave applications. Their core specifications include high sampling rates, wide bandwidth and high dynamic range, making them essential conversion components for high-end, high-frequency systems such as 5G/6G communications, RF transmitters, broadband radar and software-defined radio. This product series offers sampling rates ranging from several hundred MSPS to several GSPS, enabling the precise synthesis of wideband signals from DC to several GHz.

The high-speed DACs utilise ADI’s proprietary high-dynamic-range architecture, combined with high-speed transmission solutions such as the JESD204 high-speed serial interface and source-synchronous DDR clocks. They support multi-chip synchronised operation and are perfectly suited to multi-channel array systems. The products integrate gain and offset compensation functions, allowing direct interfacing with RF components such as quadrature modulators without the need for extensive external tuning circuits, thereby simplifying RF link design. Furthermore, even at ultra-high sampling rates, they maintain extremely low spurious-free distortion (SFDR) and a high signal-to-noise ratio (SNR), ensuring the purity and stability of high-frequency signals.

A representative model, the AD9739, is a 14-bit ultra-high-speed RF DAC with a maximum sampling rate of 2.5 GSPS. It can synthesise broadband signals ranging from DC to 3.0 GHz and supports a programmable output current of 8.7 mA to 31.7 mA, balancing high-speed performance with low power consumption; The AD9135 dual-channel high-speed DAC, with an ultra-high sampling rate of 2,800 MSPS, enables the synthesis of multi-carrier broadband signals and is suitable for high-end communication transmitter systems.

Typical applications: 5G/6G base station RF transmission, broadband software-defined radio, military radar signal synthesis, satellite communications, high-frequency test equipment, and microwave signal sources.

IV. High-Precision DACs: Ultra-High-Resolution Precision Conversion, Laying the Foundation for High-End Measurement and Control

ADI’s high-precision DACs are core components for industrial precision control and high-end measurement instruments, characterised by ultra-high resolution, ultra-low error, ultra-low temperature drift and long-term high stability. They are specifically designed for applications with the most exacting requirements for analogue output accuracy, stability and consistency. With resolutions ranging from 8-bit to 20-bit, this is one of the industry’s most comprehensive and highest-performance precision DAC product lines.

This series offers outstanding core technical advantages: ultra-low conversion error within 1 LSB, with offset and gain errors optimised to the utmost; an extremely low temperature drift coefficient, ensuring virtually no output signal drift across a wide temperature range; an extremely low noise figure, effectively eliminating distortion during the conversion of weak signals; support for single-channel to multi-channel configurations, compatibility with unipolar and bipolar outputs, and the ability to achieve millivolt-level precision in analogue output control. Furthermore, certain models are equipped with non-volatile memory functionality, enabling the retention of configuration parameters during power loss, making them suitable for long-term, uninterrupted operation.

Unlike general-purpose DACs, high-precision DACs place greater emphasis on long-term operational stability and the ability to regulate minute signals. They can precisely meet high-precision requirements such as sensor calibration, low-range control and reference source output, thoroughly resolving the pain points associated with traditional DACs—namely, insufficient accuracy, significant drift and poor consistency. Among these, the Nano DAC series, with its ultra-low power consumption, ultra-compact packaging and ultra-high precision, has become the solution of choice for high-density, miniaturised precision equipment.

Typical applications: precision measurement and control in industrial processes; high-end laboratory reference voltage/current sources; high-precision sensor calibration; medical diagnostic equipment; precise servo motion control; precision instruments for aerospace; and smart transmitters.
