Overview
The AD7192BRUZ-REEL is a 24-bit sigma-delta analog-to-digital converter (ADC) manufactured by Analog Devices Inc. This ultra-low noise ADC is designed for high precision measurement applications and features a programmable gain amplifier (PGA) and two differential or four pseudo-differential input channels. The device is capable of sampling at rates up to 4.8 kHz, making it suitable for applications requiring fast and accurate measurement of low-level analog signals. It operates with a power supply range of 3 V to 5.25 V and is housed in a 24-lead TSSOP package.
