com MS5534A ♦ ♦ ♦ ♦ BAROMETER MODULE Integrated pressure sensor Pressure range 300-1100 mbar 15 Bit ADC 6 coefficients for a software compensation stored on-chip ♦ 3-wire serial interface ♦ 1 system clock line (32.
768 kHz) ♦ Low voltage / low power DESCRIPTION The MS5534A 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.
MS5534A is a lowpower, 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.
