Overview
The AD676BD is a 16-bit parallel output analog-to-digital converter (ADC) produced by Analog Devices Inc. This multipurpose ADC utilizes a switched-capacitor/charge redistribution architecture, enabling a conversion rate of 100 kSPS with a total conversion time of 10 µs. The device is optimized for performance through on-chip autocalibration, which digitally corrects internal nonlinearities. The AD676BD is housed in a 28-pin side-brazed ceramic package and operates from +5 V and ±12 V supplies, consuming approximately 360 mW during conversion.
