Overview
The AD7605-4BSTZ-RL is a 4-channel, 16-bit, simultaneous sampling, analog-to-digital data acquisition system (DAS) produced by Analog Devices Inc. This device is designed to provide a comprehensive solution for high-precision data acquisition. It operates from a single 5 V supply and can accommodate ±10 V and ±5 V true bipolar input signals, sampling at throughput rates of up to 300 kSPS for all channels. The AD7605-4BSTZ-RL features analog input clamp protection, a second-order antialiasing filter, a track-and-hold amplifier, a 16-bit charge redistribution successive approximation analog-to-digital converter (ADC), and a 2.5 V reference and reference buffer. It also includes high-speed serial and parallel interfaces, making it compatible with SPI, QSPI™, MICROWIRE™, and digital signal processors (DSP).
