EVAL-ADAS3022EDZ Datasheet PDF - Analog Devices

GENERAL DESCRIPTION
The ADAS3022 is a complete 16-bit, 1 MSPS, successive approximation based analog-to-digital data acquisition system, which is manufactured on Analog Devices, Inc., proprietary iCMOS® high voltage industrial process technology. The device integrates an 8-channel, low leakage multiplexer; a high impedance programmable gain instrumentation amplifier (PGIA) stage with high common-mode rejection; a precision, low drift 4.096 V reference and buffer; and a 16-bit charge redistribution analog-to-digital converter (ADC) with successive approximation register (SAR) architecture.
