MS5534B

www.DataSheet4U.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.
