DESCRIPTION

The TPIC83000 is a single-channel, signal conditioning device for pressure sensors used in low-pressure

sensing applications such as passenger occupancy indication/detection and pedal pressure sensing. 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.
