AD977CN

Analog To Digital Converters (ADC) Overview

The AD977CN is a monolithic 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It features a single-ended input architecture and operates with a sampling rate of 100 kSPS. The device utilizes a serial interface for data output and requires dual 5 V power supplies for 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 is housed in a 20-pin PDIP package and supports an operating temperature range from -40°C to +85°C.
