Altimeter Module* MS5534

MS5534	Block diagram MS5534
DESCRIPTION The MS5534 pressure measurement module consists of a SMD-hybrid device including a piezoresistive pressure cell and an ADC-Interface IC. It provides 16 Bit data words from a pressure- and temperature-dependent voltage. Additionally the module contains 6 readable coefficients for a highly accurate software calibration for the pressure and temperature measurement. The MS5534 is a low-power, low-voltage device with automatic power down (ON/OFF) switching. A 3-wire interface is used to communicate with a microcontroller. The devices have a very low standby-current. The optimal compromise about refresh rate and average current consumption can individually be defined by the application software. MS5534-CM: protected by a metal ring filled with silicon gel on a ceramic hybrid 9x9mm (outdoor applications) Pressure range: 0.15 ... 16 PSI abs.; operating temperature: -40 ... +125°C MS5534-CP: protected by a plastic cap and one drop of silicon gel on a ceramic hybrid 9x9mm Pressure range: 0.15 ... 16 PSI abs.; operating temperature: -40 ... +125°C The MS5534-C is fully software compatible to previous versions (MS5534-A and MS5534-B) * Modules are pressure sensors, whose output signals have to be calculated by an external microprocessor.
FEATURES RoHS compliant Automatic Power Down Very low power consumption Ideal for battery applications High precision through individual correction data Pressure and temperature output with 16-Bit-Word Operating temperature -40 ... +125°C	APPLICATIONS Mobile Altimeter / Barometer systems Weather control systems Adventure or multi-mode watches GPS receivers Avionic control Power measurement in sports equipment Detailed application support: MEAS Switzerland S.A.
