Overview
The AD7606BSTZ-6, produced by Analog Devices Inc., is a 16-bit, simultaneous sampling, analog-to-digital data acquisition system (DAS) with six channels. This component is part of the AD7606 family, which includes the AD7606 (eight channels) and AD7606-4 (four channels). The AD7606BSTZ-6 is designed for high-speed, low-power applications and features a charge redistribution successive approximation analog-to-digital converter (ADC), along with various integrated components such as analog input clamp protection, a second-order antialiasing filter, a track-and-hold amplifier, and a flexible digital filter. It operates from a single 5 V supply and supports true bipolar input signals of ±10 V and ±5 V, sampling at throughput rates up to 200 kSPS for all channels.
