SX8723: ZoomingADC™ for Pressure and Temperature Sensing

The SX8723 is a data acquisition system based on Semtech’s low power ZoomingADC™ technology. It directly connects most types of miniature sensors with a general purpose microcontroller.

With 2 differential inputs, it can adapt to multiple sensor systems. Its digital outputs are used to bias or reset the sensing elements.
