DATASHEET
SX8722
High gain acquisition for sensor interface
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 compatible interface.
Several parameters are configurable through this interface
such as alarms or signal post processing.
Pressure sensing (industrial, altimeter, diving computer)
Chemical sensing (monitoring, security)
Magnetic sensing (compass)
