DESCRIPTION

The MS5561 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 MS5561 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.

FEATURES

APPLICATIONS

Standby current < 0.1 µA

• Mobile phones

• GPS receivers

• Altimeter applications

• Personal Navigation Devices (PND)

• Digital cameras with altimeter function

• Calibrated temperature and pressure sensor for

2^ndorder compensation

• ESD protected, HBM 4 kV
