Overview
The AD7612BCPZ-RL is a 16-bit, high-speed analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is based on the successive approximation register (SAR) architecture and is fabricated using Analog Devices' iCMOS high voltage process. It features a charge redistribution SAR ADC, an internal conversion clock, an internal reference, error correction circuits, and both serial and parallel system interface ports. The AD7612 is configurable through hardware or via a dedicated write-only serial configuration port for input range and operating mode. It operates over a temperature range of −40°C to +85°C and is available in 48-lead LFCSP and LQFP packages.
