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.

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
Programmable Resolution versus Speed versus Supply current
2 digital outputs to bias Sensors
Internal or external voltage reference
Internal time base
Low-power (250 uA for 16b @ 500 S/s)
I2C interface
