Overview
The AD7706BRUZ-REEL from Analog Devices Inc. is a 16-bit, 3-channel pseudo differential Sigma-Delta Analog-to-Digital Converter (ADC). This device is designed to serve as a complete analog front end for low-frequency measurement applications. It operates from a single supply voltage of 2.7 V to 3.3 V or 4.75 V to 5.25 V, making it versatile for various system requirements. The AD7706 features a proprietary, programmable-gain front end and an on-chip digital filter, allowing for adjustable filter cutoff and output update rates. This ADC is ideal for use in smart, microcontroller, or DSP-based systems due to its serial interface and low power consumption.
