Overview
SX8725S ZoomingADC for sensing data acquisition ADVANCED COMMUNICATIONS & SENSING DATASHEET DESCRIPTION The SX8725S 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 Digital outputs to bias Sensors Internal or external voltage reference Internal time base Low-power (250 uA for 16b @ 250 S/s) SPI interface, 2 Mbps serial clock www.
