ZoomingADC for sensing data acquisition

DATASHEET

DESCRIPTION

The SX8723S 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

Industrial chemical sensing

Barometer

Compass

FEATURES

Up to 16-bit differential data acquisition

Programmable gain: (1/12 to 1000)

Sensor offset compensation up to 15 times full scale

of input signal

2 differential or 4 single-ended signal inputs
