Overview
The AD676JNZ 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, achieving 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 AD676JNZ is packaged in a 28-pin plastic DIP and is suitable for a variety of signal processing and measurement applications.
