Overview
The AD7607BSTZ-RL, produced by Analog Devices Inc., is a 14-bit, simultaneous sampling, analog-to-digital data acquisition system (DAS). This device is designed to provide high-performance data acquisition with multiple channels. It operates from a single 5 V supply and supports true bipolar input signals of ±10 V and ±5 V, with sampling rates up to 200 kSPS for all channels. The AD7607 includes features such as analog input clamp protection, a second-order antialiasing filter, a track-and-hold amplifier, a 14-bit charge redistribution successive approximation analog-to-digital converter (ADC), and high-speed serial and parallel interfaces.
