Overview
The AD7616BSTZ is a 16-channel Data Acquisition System (DAS) produced by Analog Devices Inc. This device is designed for high-performance data acquisition and supports dual simultaneous sampling of 16 channels. It operates from a single 5 V supply and can accommodate true bipolar input signals ranging from ±10 V, ±5 V, to ±2.5 V. The AD7616 features a dual 16-bit successive approximation register (SAR) analog-to-digital converter (ADC) with throughput rates up to 1 MSPS per channel pair and achieves a signal-to-noise ratio (SNR) of 90.5 dB at 1 MSPS. Higher SNR performance of 92 dB can be achieved with the on-chip oversampling mode.
