Overview
The AD7616-PBSTZ is a 16-channel, 16-bit data acquisition system (DAS) produced by Analog Devices Inc. This device supports dual simultaneous sampling of 16 channels and operates from a single 5 V analog supply and a 2.3 V to 3.6 V VDRIVE supply. It is designed to accommodate true bipolar input signals of ±10 V, ±5 V, and ±2.5 V, making it versatile for various industrial and instrumentation applications. The AD7616-P features high signal-to-noise ratio (SNR) performance, with up to 90.5 dB SNR at 1 MSPS and 92 dB SNR with an oversampling ratio (OSR) of 2.
