SX8725

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. 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 Ordering Information Device Package Reel quantity 3000 1000 SX8725E083TRT MLPD-W-12 4x4 SX8725E083TDT MLPD-W-12 4x4 1) Available in tape and reel only 2) Lead free, WEEE and RoHS compliant.
