AD9023AZ - 12-Bit 20 MSPS Parallel ADC | Analog Devices
MPN: AD9023AZ ✓ ActiveAD9023AZ Overview
An ADC is an analog-to-digital converter, a semiconductor that samples an analog voltage and converts it into a proportional digital code. ADCs sit at the boundary between sensors, amplifiers, and digital processing systems. The AD9023AZ belongs to the parallel-output ADC family, where each conversion produces a multi-bit value through a parallel interface rather than a serial data stream. This architecture can simplify connections to parallel FPGA, DSP, or data-capture circuitry when sufficient board routing space is available.
The verified product information identifies three principal performance characteristics: 12-bit resolution, a maximum sampling rate of 20 MSPS, and a maximum linearity error of 0.0732%. The 12-bit format provides 4,096 discrete codes, while the 20 MSPS capability permits 20 million conversion results per second. These figures make the device relevant to waveform capture, communications, industrial monitoring, and other systems in which the sample rate and digital word width must be balanced against routing complexity.
Parallel word access distinguishes the AD9023AZ from serial-interface converters. Parallel output can provide direct multi-bit transfer between the converter and receiving logic, although the 28-terminal package requires careful routing and signal-integrity control. Engineers should preserve the device's specified analog and digital supply requirements, reference arrangement, clocking method, and input settling conditions, but those detailed electrical parameters are not present in the supplied verified data and must be confirmed in the manufacturer datasheet before implementation.
Typical application opportunities include digital oscilloscope and waveform-capture front ends, communications receivers, industrial process monitoring, medical instrumentation, and control systems. The 20 MSPS rate supports moderate-bandwidth digitization, while the 12-bit resolution offers a practical balance between conversion accuracy, interface width, storage requirements, and processor capacity. Applications requiring substantially higher rates, resolution, or serial data transfer should use a different converter architecture.
A primary design consideration is the parallel-data routing burden. Traces carrying adjacent digital output bits should be length-matched where practical, clocks should be routed cleanly, and analog input circuitry should be isolated from switching and high-current digital paths. Power and decoupling recommendations must follow the official manufacturer documentation rather than values inferred from marketplace listings.
This page consolidates the verified AD9023AZ resolution, sampling rate, linearity, temperature, inventory, and pricing information with application guidance and engineering considerations. It also identifies where datasheet confirmation is still required, avoiding unsupported claims about voltages, pin assignments, package dimensions, and drop-in replacements.

Typical Applications
AD9023AZ is suitable for 6 applications: Digital Oscilloscope and Waveform Capture, Communications Receiver and Baseband Sampling, Industrial Process Monitoring, Medical Instrumentation and Diagnostic Equipment, FPGA-Based Digital Signal Processing, Audio and Control Signal Digitization.
Digital Oscilloscope and Waveform Capture
The AD9023AZ fits moderate-bandwidth digital waveform-acquisition systems because it converts at up to 20 MSPS while delivering a 12-bit parallel code. A parallel interface can feed an FPGA or DSP directly when channel count, trace length, and routing space permit. The front end still requires a suitable input amplifier, anti-alias filter, reference network, and clock source. Engineers must confirm the complete input range, acquisition time, and clock requirements in the manufacturer datasheet before calculating vertical resolution or expected bandwidth.
Communications Receiver and Baseband Sampling
The AD9023AZ can serve as the sampling element in a communications receiver when its 20 MSPS conversion rate and 12-bit resolution meet the required bandwidth and signal-to-noise budget. Parallel outputs may reduce the need for a high-speed serial link between the converter and FPGA or DSP, but they increase board routing complexity. The receiver design should verify input common mode, full-scale range, reference accuracy, clock jitter, and digital interface timing against the official datasheet before selecting the converter.
Industrial Process Monitoring
For industrial process monitoring, the AD9023AZ provides a confirmed 12-bit conversion format and 20 MSPS maximum sampling rate for acquiring rapidly changing sensor or control signals. Those characteristics can support data acquisition, machine vision assistance, and condition-monitoring front ends when the analog bandwidth is sufficient. Industrial deployments should also account for the -25°C to +85°C operating range, grounding and isolation requirements, calibration strategy, and long-term availability of the selected package and ordering suffix.
Medical Instrumentation and Diagnostic Equipment
The AD9023AZ may be evaluated for low- to moderate-bandwidth medical instrumentation that requires deterministic parallel digital data at up to 20 MSPS. Its 12-bit result width provides 4,096 codes, giving designers a defined starting point for analyzing whether the required signal amplitude and noise floor can be resolved. Medical applications require additional attention to patient isolation, safety boundaries, input protection, calibration, and regulatory validation; no medical or AEC-Q100 qualification is stated in the supplied data.
FPGA-Based Digital Signal Processing
The AD9023AZ is suitable for an FPGA-centered acquisition chain where a 12-bit parallel result can be captured without relying on a serial interface. At 20 MSPS, the digital channel must continuously accept and route valid conversion data with the timing margins defined by the device and FPGA I/O standards. Engineers should determine the required logic levels, clock topology, output timing, voltage thresholds, and synchronization method from the official datasheets for both devices before finalizing the PCB interface.
Audio and Control Signal Digitization
The AD9023AZ can digitize audio-frequency or control signals where a 20 MSPS sampling capability exceeds the basic bandwidth requirement and a 12-bit parallel output is acceptable. Oversampling relative to the signal bandwidth can provide filtering margin, but the usable dynamic range still depends on analog noise, reference accuracy, linearity, and the front-end signal level. A low-noise input amplifier, suitable anti-alias filter, clock source, and FPGA or DSP capture stage should be evaluated together rather than treating converter resolution as the complete system accuracy.

Key Differentiators

- Published maximum linearity figure (vs AD9023ARU)
- Broadly stated operating-temperature range (vs AD8021ARZ-REEL7)
Design Notes
Treat the parallel data bus as a high-speed digital interface even though the converter is not specified as a serial-link device. Route output groups with consistent geometry, minimize stubs and unnecessary vias, use a continuous reference plane, and confirm receiver thresholds and trace-impedance requirements. The verified data identifies 28 terminals but does not provide pin assignments, so the land pattern and every bus connection must be verified against the current manufacturer package drawing before fabrication.
Separate the sensitive analog input and reference paths from digital output and clock routing to reduce conversion error and coupling. Use a continuous ground reference, keep return paths short, and place decoupling and input-network components according to the official reference layout. Exact capacitance, resistance, reference arrangement, and clock topology are unavailable in the supplied records and should not be guessed.
Do not select a replacement from the MPN suffix alone. The cross-reference results mention AD9023AQ, AD9023ARU, and AD8021ARZ-REEL7 as evaluation candidates but do not verify package dimensions, pin functions, electrical limits, or ordering temperature grades. A production substitution requires a side-by-side datasheet review covering supply voltage, input range, reference, clock, output timing, and PCB land pattern.
Compliance Information
