AD977ARZ-REEL

Analog To Digital Converters (ADC) Overview

The AD977ARZ-REEL is a single-channel, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates with a sampling rate of 100 kSPS and accepts single-ended input signals. The device utilizes a serial interface for data communication and is powered by dual 5 V supplies for both analog and digital sections. Key performance metrics include an 85 dB signal-to-noise ratio, +/- 3 LSB integral nonlinearity, and +/- 2 LSB differential nonlinearity. It functions within a temperature range of -40°C to +85°C and is housed in a 20-pin SOIC surface-mount package.
