Overview
The AD7605-4BSTZ, produced by Analog Devices Inc., is a 4-channel, 16-bit, simultaneous sampling analog-to-digital data acquisition system (DAS). This device is designed to provide a fully integrated solution for various high-precision data acquisition applications. It operates from a single 5 V supply and can accommodate true bipolar input signals up to ±10 V and ±5 V, sampling at throughput rates of up to 300 kSPS for all channels. The AD7605-4 features on-chip analog input clamp protection, a second-order antialiasing filter, and a high-speed serial and parallel interface compatible with SPI, QSPI, MICROWIRE, and DSPs.
