Altimeter Pressure Sensor MS5561

DESCRIPTION

The MS5561 is a SMD-hybrid device including a precision piezoresistive pressure sensor and an ADC-Interface IC.  It uses a 3-wire serial interface for communication.  The module dimensions of 4.75 mm X 4.25 mm and a height of only 1.6 mm allows for up-to-date SMD design.  It provides a 16 bit data word from a pressure and temperature dependent voltage.  The MS5561 is a low power, low voltage decide with automatic power down (ON/OFF) switching.  A 3-wire interface is used for all communications with a micro-controller.
