MS5534B General Description
The MS5534B 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. MS5534B 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. Sensor packaging options are plastic or metal cap.
Compared to the previous version (MS5534A) the temperature range has been improved (-40 to +125) as well as the pressure range (measurement down to 10 mbar). Other improvements concern the ESD sensitivity, current consumption and converter accuracy.
