The pressure sensor can be based on either a strain gauge or piezo-resistive elements configured as a full Wheatstone bridge.
This device provides an analog signal conditioning interface between the pressure sensor and a microcontroller.
The analog front end (AFE) inside the device processes the sensed signals from the pressure sensor by amplifying the signal and cancelling offset.
This processed signal is then converted into a 14-bit, digital word using a sigma-delta analog-to-digital converter (ADC).
The device also has a built-in 12-bit ADC that is used to sense ambient temperature to compensate for the temperature coefficient of the sensor and related processing circuitry.
The compensated digital data is transferred to the microprocessor via a built-in UART interface.
