ZoomingADC for sensing data acquisition
DATASHEET
DESCRIPTION
FEATURES
The SX8724C is a data acquisition system based on
Up to 16-bit differential data acquisition
Semtech's low power ZoomingADC™ technology. It
Programmable gain: (1/12 to 1000)
directly connects most types of miniature sensors
with a general purpose microcontroller.
r _{With 3 differential inputs, it can adapt to multiple}
o ^{sensor systems. Its digital outputs are used to bias or}
f reset the sensing elements.
