AD976AACHIPS

Analog To Digital Converters (ADC) Overview

The AD976AACHIPS is a discontinued 16-bit analog-to-digital converter (ADC) from Analog Devices, part of the AD976A series. It utilizes a successive approximation register (SAR) architecture with a switched capacitor structure and operates on a single 5 V supply. The device features a high-speed parallel interface and an internal 2.5 V reference. Key electrical parameters include a throughput rate of 200 kSPS, a maximum power dissipation of 100 mW, and an analog full-scale input range of ±10 V. It offers a signal-to-noise ratio of 85 dB, differential nonlinearity of -2 LSB/3 LSB, integral nonlinearity of +/- 3 LSB, and gain error of +/- 0.5% FSR. The component is housed in a 28-lead skinny DIP package and supports operation temperatures from -40°C to +85°C.
