General Description
The MPS-300A series pressure sensor is a hybrid device containing an absolute piezoresistive pressure sensing element and
an ASIC for signal conditioning. The sensor element is fabricated using bulk micromachining technology.
The ASIC includes temperature and nonlinearity corrections as well as offset and span calibration incorporating a 16 bit
digital signal path. The device is digitally calibrated and tested over temperature to ensure that the relevant accuract
and stability performance is met.
Output options include digital interfaces such as SPI and I2C as well as the traditional analogue output that can be
interfaced to an external ADC. Temperature readout is optionally available on digital SPI and I2C interface options.
