Overview
The AD7606C-18BSTZ is an 18-bit, simultaneous sampling, analog-to-digital data acquisition system (DAS) produced by Analog Devices Inc. This component features eight channels, each equipped with analog input clamp protection, a programmable gain amplifier (PGA), a low-pass filter (LPF), and an 18-bit successive approximation register (SAR) analog-to-digital converter (ADC). It operates from a single 5 V supply and includes a flexible digital filter, a low drift 2.5 V precision reference, and a reference buffer to drive the ADC. The device supports both parallel and serial interfaces, making it versatile for various applications.
