ZoomingADC™ for Pressure and Temperature Sensing

ADVANCED COMMUNICATIONS & SENSING

Description

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.

Applications

• Industrial pressure sensing

• Industrial temperature sensing

• Barometer

• Compass
