SX8724
ZoomingADC⢠for Pressure and Temperature Sensing
ADVANCED COMMUNICATIONS & SENSING
Description
The SX8724 is a data acquisition system based on
Semtechâs low power ZoomingADC⢠technology. It
directly connects most types of miniature sensors
with a general purpose microcontroller.
With 3 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
⢠Barometer
⢠Compass
