Overview
The AD7714ARSZ-3 is a high-resolution, 24-bit Sigma-Delta analog-to-digital converter (ADC) produced by Analog Devices Inc. This component is designed to provide precise digital conversion of analog signals and is particularly suited for applications requiring high accuracy and low power consumption.
The AD7714ARSZ-3 features three differential analog inputs, which can also be configured as five pseudo-differential analog inputs, along with a differential reference input. It is ideal for use in smart microcontroller- or DSP-based systems due to its serial interface and software-configurable settings for gain, signal polarity, and channel selection.
