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
