MS5534C (RoHS^*)

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

• 16 Bit ADC

• 3-wire serial interface

• 1 system clock line (32.768 kHz)

• Low voltage and low power consumption

• RoHS-compatible & Pb-free^*

DESCRIPTION

The 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 4kV on all pins.
