SX8725
ZoomingADC™ for Pressure and Temperature Sensing
ADVANCED COMMUNICATIONS & SENSING
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.
Applications
• Industrial pressure sensing
• Industrial temperature sensing
• Barometer
• Compass
