Product Introduction
The AD7705 is a 16-bit ADC designed for low-frequency measurement applications, capable of directly converting small sensor output signals. The device features two fully differential input channels and communicates via a 3-wire SPI interface. It integrates a configurable analog front-end gain, signal polarity setting, and output rate control. The device supports self-calibration and system calibration to effectively eliminate gain and offset errors from both the device itself and the system. It also offers high resolution, excellent noise immunity, low voltage operation, and low power consumption.
