Overview
The AD7193BRUZ-REEL, produced by Analog Devices Inc., is a highly advanced, low noise, 24-bit sigma-delta (Σ-Δ) analog-to-digital converter (ADC) designed for high precision measurement applications. It serves as a complete analog front end, incorporating a low noise gain stage that allows signals of small amplitude to interface directly with the ADC. This device is particularly useful in scenarios where high accuracy and low noise are critical.
