AD977AARS

Analog To Digital Converters (ADC) Overview

The AD977AARS is a high-speed, low-power 16-bit analog-to-digital converter manufactured by Analog Devices Inc. It utilizes a successive approximation switched-capacitor architecture and operates from a single 5 V supply with a maximum power dissipation of 100 mW. The device features a throughput rate of 200 kSPS and includes an internal 2.5 V reference along with a high-speed serial interface. Factory calibration minimizes linearity errors, supporting input ranges including ±10 V, ±5 V, ±3.3 V, and unipolar options.
