SX8722 Datasheet | SEMTECH

High gain acquisition for sensor interface ADVANCED MUNICATIONS & SENSING GENERAL DESCRIPTION The main function of the SX8722 is to acquire signal from Wheatstone bridges or single ended sensors. The input can be a pressure sensor, a GMR or AMR magnetic sensor, a chemical sensor, a thermistor or a mix of several of these sensors. The SX8722 Sensor interface is totally configurable through an I2C patible interface. Several parameters are configurable through this interface such as alarms or signal post processing.
