Overview
The AD7710AR-REEL7, produced by Analog Devices Inc., is a 24-bit, sigma-delta analog-to-digital converter (ADC) designed for low-frequency measurement applications. This device serves as a complete analog front end, capable of accepting low-level signals directly from strain gages or transducers and outputting a serial digital word. It features a programmable gain front end, differential inputs, and a low-pass filter with programmable filter cutoffs, making it ideal for use in smart, microcontroller-based systems.
