Overview
The AD7606BSTZ-4, manufactured by Analog Devices Inc., is a 4-channel, 16-bit, simultaneous sampling analog-to-digital data acquisition system (DAS). This component is part of the AD7606 family, which includes variants with 8, 6, and 4 channels. The AD7606BSTZ-4 is designed for high-speed, low-power applications and features a charge redistribution successive approximation analog-to-digital converter (ADC).
It operates from a single 5 V supply and can handle true bipolar input signals up to ±10 V and ±5 V. The device includes analog input clamp protection, a second-order antialiasing filter, a track-and-hold amplifier, and a flexible digital filter. This makes it an integrated solution for various data acquisition needs without requiring external bipolar supplies or driver op-amps.
