MS5561C

The MS5561C is a SMD-hybrid device including a precision
piezo-resistive pressure sensor and an ADC-Interface IC. It uses
a three-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
MS5561C 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 micro-controller.
