AD977CRZRL

Analog To Digital Converters (ADC) Overview

The AD977CRZRL is a single-channel, 16-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates with a sampling rate of 100 kS/s and features a serial interface for data output. The device supports single-ended input signals and functions within an ambient temperature range of -40°C to +85°C. Power requirements include both analog and digital supply voltages of 5 V, resulting in a typical power dissipation of 100 mW. Key performance metrics specify a signal-to-noise ratio (SNR) of 85 dB, differential nonlinearity (DNL) of ±2 LSB, integral nonlinearity (INL) of ±3 LSB, and a gain error of ±0.5% FSR. The component is housed in a 20-lead SOIC package designed for surface mount technology.
