Overview
The AD7606BSTZ-RL, manufactured by Analog Devices Inc., is a 16-bit, simultaneous sampling, analog-to-digital data acquisition system (DAS). This device is part of the AD7606 family, which includes variants with eight, six, and four channels. The AD7606BSTZ-RL specifically features eight channels. It operates from a single 5 V supply and supports true bipolar analog input ranges of ±10 V and ±5 V. The device is designed for high-speed data acquisition, sampling at throughput rates up to 200 kSPS for all channels.
The AD7606BSTZ-RL includes several key components such as 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), a flexible digital filter, and a 2.5 V reference and reference buffer. It also features high-speed serial and parallel interfaces, making it versatile for various applications.
