com MS5534B BAROMETER MODULE • 10 - 1100 mbar absolute pressure range • 6 coefficients for software compensation stored on-chip • Piezoresistive silicon micromachined sensor • Integrated miniature pressure sensor 9 x 9 mm • 15 Bit ADC • 3-wire serial interface • 1 system clock line (32.
768 kHz) • Low voltage and low power consumption • RoHS-compatible & Pb-free1 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° C) as well as the pressure range (measurement down to 10 mbar).
Other improvements concern the ESD sensitivity, current consumption and converter accuracy.
FEATURES • Supply voltage 2.
