MS5534B Datasheet | Unknown Manufacturer

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 munications with a microcontroller. Sensor packaging options are plastic or metal cap. pared 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 2.2 V to 3.6 V - Low supply current - -40° C to +125° C operation temperature - No external ponents required APPLICATIONS - Mobile altimeter / barometer systems - Weather control systems - Adventure or multi-mode watches - GPS receivers BLOCK DIAGRAM VDD MCLK Digital Interface ADC dig.
