Altimeter Miniature Module* MS5561C

MS5561	Block diagram MS5561
DESCRIPTION The MS5561C pressure measurement miniature 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 MS5561C 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. MS5561-CM: protected by a metal cap filled with silicon gel on a ceramic hybrid 6.2x6.4mm² Pressure range: 10...1100mbar (0.15 ... 16 PSI) abs.; operating temperature: -40 ... +85°C. *Modules are pressure sensors, whose output signals have to be calculated by an external microprocessor.
FEATURES Resolution 0.1mbar Supply voltage 2.2...3.3V Automatic Power Down Very low power consumption (Stand by <0.1μA Ideal for battery applications 3 wires serial interface High precision through individual correction data Pressure and temperature output with 16-Bit-Word Operating temperature -40 ... +85°C RoHS compliant and Pb free	APPLICATIONS Mobile Altimeter / Barometer systems Weather control systems Adventure or multi-mode watches GPS receivers Avionic control Detailed application support: MEAS Switzerland S.A.
