Product details
Overview
ADAS3022SCPZ-EP from Analog Devices is a 16-bit, 1 MSPS, 8-channel SAR-based data acquisition system integrating an 8-channel multiplexer, programmable gain instrumentation amplifier (PGIA), on-chip 4.096 V reference, and precision ADC. It supports ±24.576 V differential input range with >500 MΩ input impedance and >100 dB common-mode rejection, deployed in defense-grade power line monitoring and multichannel process control systems.
For engineers reviewing the ADAS3022SCPZ-EP datasheet, ADAS3022SCPZ-EP pinout, ADAS3022SCPZ-EP application, or ADAS3022SCPZ-EP equivalent, key selection factors include military temperature range (−55°C to +105°C), enhanced product qualification for aerospace/defense, no pipeline delay, SPI-/SPORT-compatible 4-wire interface, and support for eight single-ended or four fully differential inputs.
Technical Context
The ADAS3022SCPZ-EP employs a successive approximation register (SAR) architecture delivering zero-latency conversion results with immediate data availability post-conversion. Its integrated PGIA provides user-programmable gains (0.16 to 6.4) and high common-mode rejection (>100 dB at 2 kHz), enabling direct sensor interfacing without external signal conditioning.
It features dual reference paths-internal 4.096 V buffered reference (±5 ppm/°C drift) and external REFx/REFIN support-and operates from ±15 V high-voltage analog supplies (VDDH/VSSH) with independent 5 V digital (AVDD/DVDD) and 1.8–5 V I/O (VIO) rails. The device includes auxiliary ADC inputs (AUX+/AUX−) and on-die temperature sensing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision, multichannel data acquisition applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADAS3023BCPZ | Commercial-grade variant; same architecture but rated for −40°C to +85°C only; lacks AQEC qualification and military temp range | Not suitable for defense/aerospace deployment; acceptable for industrial ATE or lab instrumentation | Select ADAS3023BCPZ only when military qualification and extended temperature operation are not required |
| AD7606C-16BSTZ | 8-channel, 16-bit, 1 MSPS SAR ADC with integrated analog front end but no PGIA; fixed ±10 V input range; no auxiliary ADC input | Lacks programmable gain and auxiliary channel; requires external amplification for low-level sensor signals | Choose AD7606C-16BSTZ when cost-sensitive designs accept external signal conditioning and do not require gain flexibility or AUX+/- capability |
Compared with ADAS3022SCPZ-EP, ADAS3023BCPZ omits defense-grade qualification and temperature range, while AD7606C-16BSTZ trades PGIA integration and auxiliary inputs for lower unit cost and simpler power architecture-making ADAS3022SCPZ-EP uniquely suited for ruggedized, gain-flexible, single-chip DAQ in mission-critical systems.

FAQ
What is the maximum differential input voltage supported by the ADAS3022SCPZ-EP?
The ADAS3022SCPZ-EP supports a maximum differential input voltage of ±24.576 V when using ±15 V analog supplies (VDDH/VSSH) and appropriate PGIA gain settings. This range is achieved with PGIA gain = 0.16 and ±15 V supplies, as specified in the General Description and Table 2 of the datasheet. Higher gains reduce the allowable input span proportionally.
Does the ADAS3022SCPZ-EP include an internal voltage reference?
Yes, the ADAS3022SCPZ-EP integrates a precision 4.096 V internal reference with buffer, specified at 4.088 V to 4.104 V at 25°C and ±5 ppm/°C drift when REFEN = 1. REF1 and REF2 pins provide this reference externally and require individual 10 μF ceramic decoupling capacitors per the Pin Configuration section.
What is the operating temperature range for the ADAS3022SCPZ-EP?
The ADAS3022SCPZ-EP is qualified for operation from −55°C to +105°C, meeting military temperature specifications and AQEC standards for defense and aerospace applications. This extended range is explicitly stated in the Enhanced Features section and confirmed in the Temperature Range specification table (Page 7).
How many analog input channels does the ADAS3022SCPZ-EP support, and what configurations are possible?
The ADAS3022SCPZ-EP supports eight analog input channels (IN0–IN7) that can be configured as eight single-ended inputs or four fully differential pairs. The COM pin serves as the common reference point, and Table 1 in the datasheet lists supported input ranges for both differential and single-ended modes across multiple PGIA gain settings.
Is the ADAS3022SCPZ-EP compatible with standard SPI interfaces?
Yes, the ADAS3022SCPZ-EP features a 4-wire SPI-/SPORT-compatible digital interface with CS, SCK, DIN, and SDO pins. It operates with VIO from 1.8 V to 5 V, supports standard SPI timing (tSCK ≥ 15 ns), and delivers conversion results on SCK falling edges in twos complement format-enabling direct connection to FPGAs and microcontrollers without protocol translation.
