Overview
The AD7606C-18BSTZ-RL is an 18-bit, simultaneous sampling, analog-to-digital data acquisition system (DAS) manufactured 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 analog supply and supports a range of input configurations, including bipolar single-ended, unipolar single-ended, and bipolar differential inputs. The AD7606C-18 is designed for high-performance applications requiring precise and simultaneous sampling of multiple analog signals.
