SX8723C

SX8723C ZoomingADC for sensing data acquisition ADVANCED COMMUNICATIONS & SENSING DATASHEET DESCRIPTION The SX8723C 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 2 differential inputs, 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 2 differential or 4 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) Fast I2C interface with external address option, no clock stretching required www.DataSheet4U.com APPLICATIONS Industrial pressure sensing Industrial temperature sensing Industrial chemical sensing Barometer Compass ORDERING INFORMATION DEVICE SX8723CWLTDT PACKAGE MLPD-W-12 4x4 REEL QUANTITY 1000 - Available in tape and reel only - WEEE/RoHS compliant, Pb-Free and Halogen Free.
