Overview
The AD7606BSTZ, produced by Analog Devices Inc., is a 16-bit, simultaneous sampling, analog-to-digital data acquisition system (DAS) with eight channels. This component is part of the AD7606 family, which includes variants with six and four channels (AD7606-6 and AD7606-4, respectively). The AD7606BSTZ operates from a single 5 V supply and can accommodate true bipolar input signals of ±10 V and ±5 V while sampling at throughput rates up to 200 kSPS for all channels.
The device features on-chip filtering, high input impedance, and input clamp protection, eliminating the need for external driver op amps and bipolar supplies. It includes a second-order antialiasing filter, a track-and-hold amplifier, a 16-bit charge redistribution successive approximation analog-to-digital converter (ADC), a flexible digital filter, and high-speed serial and parallel interfaces.
