Overview
The ADAS3022SCPZ-EP-RL is a high-performance, low-power, multichannel analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is part of the ADAS3022 series and is specifically designed for enhanced reliability and performance in demanding environments. It features a 16-bit resolution and a sampling rate of up to 1 MSPS, making it suitable for a wide range of data acquisition and measurement applications.
The ADAS3022SCPZ-EP-RL integrates an 8-channel, low leakage multiplexer, a high impedance programmable gain instrumentation amplifier (PGIA) stage, a precision 4.096 V reference and buffer, and a 16-bit charge redistribution analog-to-digital converter with a successive approximation register (SAR) architecture. This integration simplifies design challenges by eliminating the need for external signal buffering, level shifting, amplification/attenuation, and common-mode rejection.
