DescriptionThe MS5534C is a SMD-hybrid device including a piezoresistive pressure sensor and an ADC-Interface IC. It provides a 16 Bit data word from a pressure and temperature dependent voltage. Additionally the module contains 6 readable coefficients for a highly accurate software calibration of the sensor. MS5534C is a low power, low voltage device with automatic power down (ON/OFF) switching. A 3-wire interface is used for all communications with a microcontroller. The MS5534C is fully software compatible to the previous versions (MS5534A and MS5534B). Compared to the previous versions the ESD sensitivity level has been improved to 4 kV on all pins.
