I. Core Advantages of ADI ADC/DAC Combination Converters (Integrated General-Purpose Features)

Compared to signal chains built using discrete ADC and DAC components, ADI’s integrated combination converters offer general-purpose core advantages, which are the key reasons for their adoption as alternatives to discrete solutions. Firstly, they offer high integration and miniaturisation: a single chip integrates transmission and reception conversion channels, clock circuits, power monitoring and digital interfaces, significantly reducing PCB area, the number of peripheral components and the complexity of routing; Secondly, they provide high system consistency: the on-chip ADC and DAC share a clock reference and power domain, avoiding issues such as clock drift, phase mismatch and noise interference associated with discrete components, thereby greatly enhancing the stability of the signal chain; Finally, there is flexible configurability: the entire range supports software-configurable inputs and outputs (SWIO), allowing on-demand switching of channel operating modes, sampling rates and signal bandwidth to adapt to dynamic requirements across multiple scenarios. At the same time, the integration of on-chip monitoring and control modules simplifies system operation, maintenance and fault detection.

II. High-Speed ADC/DAC Combination Converters (High-Speed RF Series)

ADI’s high-speed ADC/DAC combination converters feature ultra-high sampling rates, ultra-wide RF bandwidth and high-speed real-time signal processing as their core characteristics. They are primarily targeted at RF and microwave applications, 5G/6G communications, software-defined radio, quantum measurement and control, and aerospace broadband signal acquisition and transmission scenarios. At the heart of this series lies the Apollo MxFE (Mixed-Signal Front-End) platform, the industry’s first integrated RF transceiver conversion chip. It overcomes the bandwidth and speed limitations of traditional discrete high-speed converters and supports direct RF sampling and RF output without the need for multi-stage frequency conversion circuits.

2.1 Key Technical Features

- Ultra-high sampling rates: The DAC core achieves a maximum sampling rate of 28 GSPS, whilst the ADC core reaches up to 20 GSPS, supporting ultra-high-speed continuous signal conversion and meeting the requirements for Ku-band RF signal processing;

- Ultra-wide signal bandwidth: Supports an RF input bandwidth of DC to 18 GHz, with an instantaneous signal bandwidth of up to 10 GHz, enabling the direct acquisition and transmission of multi-band, wideband signals, thereby eliminating the need for intermediate frequency (IF) conversion;

- Multi-channel integrated architecture: Mainstream models adopt a multi-transmit/receive (T/R) architecture, supporting synchronous operation of 4 or 8 channels, suitable for array signal processing and multi-carrier communication scenarios;

- On-chip DSP acceleration: Integrates signal processing units such as digital filtering, interpolation, decimation and phase calibration, enabling basic signal pre-processing without the need for an external FPGA, thereby reducing the system’s computational load;

- Low latency and high synchronisation: On-chip channel clocks are synchronised from a common source, resulting in minimal conversion latency deviation across multiple channels, meeting high-synchronisation requirements such as high-speed beamforming and quantum-precision timing control.

2.2 Typical Core Models and Specifications

ADI’s high-speed combined converters are centred on the Apollo MxFE series, covering a range of data rates and channel configurations to suit high-speed applications at various levels:

- AD9084: A flagship 4T4R architecture featuring four 16-bit 28 GSPS RF DACs and four 12-bit 20 GSPS RF ADCs, with an instantaneous bandwidth of 10 GHz; it serves as a core component for quantum measurement and control, as well as next-generation broadband communications;

- AD9088: An 8T8R multi-channel architecture comprising 8-channel 16-bit 16 GSPS DACs and 8-channel 12-bit 8 GSPS ADCs, designed primarily for multi-channel array RF signal transmission and reception, and suitable for base station arrays and broadband radar systems;

- AD9082: A 4-channel, 16-bit, 12 GSPS DAC and dual 12-bit, 6 GSPS ADCs, offering excellent value for money and widely used in commercial software-defined radio and broadband signal test equipment;

- AD9081: 4-channel 16-bit 12 GSPS DAC and 4-channel 12-bit 4 GSPS ADC; supports multi-band signal multiplexing and is suitable for small-to-medium-sized broadband communication equipment and portable high-speed measurement and control instruments;

- AD9961/AD9963: Entry-level, low-power, high-speed models featuring a 2-channel 100 MSPS ADC and a 2-channel 170 MSPS DAC, supporting clock multiplication configurations; suitable for low-cost, high-speed industrial communications and general-purpose signal acquisition systems.

2.3 Core Application Scenarios

This series focuses on the fields of high-speed, broadband and real-time signal processing. It is primarily used in equipment such as 5G/6G macro base stations, distributed radio frequency units, software-defined radio (SDR), broadband radar detection, quantum bit control and readout, aerospace broadband signal acquisition, and high-precision, high-speed signal simulators, effectively addressing the pain points of traditional discrete solutions, such as insufficient bandwidth, excessive latency and complex cabling.

III. High-Precision ADC/DAC Combination Converters (Precision Measurement Series)

ADI’s high-precision ADC/DAC combination converters offer high resolution, low noise, low drift and high linearity as their core advantages. By prioritising signal conversion precision and stability over extreme sampling rates, they are designed for applications such as industrial automation, precision instruments, sensor calibration, power supply monitoring, medical equipment and process control—where signal accuracy, temperature drift and noise performance are critical. This series of devices is designed for medium- to low-speed precision conversion, with its core strengths lying in the acquisition of weak signals and the precise control of minute analogue outputs.

- Ultra-high conversion resolution: Mainstream resolutions range from 12 to 24 bits, enabling the precise acquisition and output of weak analogue signals at the microvolt level to meet precision measurement requirements;

- Extremely low noise and temperature drift: Utilising ADI’s proprietary precision analogue process, these devices feature extremely low input noise and minimal temperature drift coefficients; signal conversion error is negligible across the entire temperature range, making them suitable for complex industrial environments with high and low temperatures;

- High linearity and low distortion: Differential non-linearity (DNL) and integral non-linearity (INL) errors approach zero, ensuring excellent conversion linearity without signal distortion or step-response issues;

- Low power consumption and high stability: Optimised specifically for low-power industrial applications, supporting long-term continuous and stable operation, with overvoltage, overcurrent and overheat protection, and strong resistance to electromagnetic interference;

- Multi-channel synchronous precision conversion: Supports synchronous multi-channel ADC acquisition and synchronous multi-channel DAC output, suitable for multi-sensor array calibration and multi-channel analogue closed-loop control systems.

3.2 Core Functions and Product Features

The high-precision combined converter integrates a precision operational amplifier, reference voltage source and filter circuit, enabling high-precision conversion without the need for an external precision reference source, thereby significantly simplifying the design of precision signal chains. It also supports software configuration of gain, offset and sampling period, making it suitable for the acquisition of various sensor signals such as voltage, current and resistance. Combining signal monitoring with analogue output control capabilities, it is widely used in scenarios such as system parameter calibration, closed-loop regulation and status monitoring. Compared to discrete precision ADCs and DACs, the single-chip solution offers higher channel matching and better batch consistency, effectively reducing system calibration costs.
