Description

The SX8725 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 1 differential input, 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

• 1 differential or 2 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)

• 2-WIRE interface

Applications

• Industrial pressure sensing

• Industrial temperature sensing

• Barometer

• Compass
