MS5803-02BA

Miniature Altimeter Module

SPECIFICATIONS



High resolution module, 20cm

Fast conversion down to 1 ms

Low power, 1 µA (standby < 0.15 µA)

Integrated digital pressure sensor (24 bit ΔΣ ADC)

Supply voltage 1.8 to 3.6 V

Operating range: 300 to 1100 mbar, -40 to +85 °C

Hermetically sealable for outdoor devices

The MS5803-02BA is a new generation of high resolution

altimeter sensors from MEAS Switzerland with SPI and I²C bus

interface. It is optimized for altimeters and variometers with an

altitude resolution of 20 cm. The sensor module includes a high

linearity pressure sensor and an ultra low power 24 bit ΔΣ ADC

with internal factory calibrated coefficients. It provides a precise

digital 24 Bit pressure and temperature value and different

operation modes that allow the user to optimize for conversion

speed and current consumption. A high resolution temperature

output allows the implementation of an altimeter/thermometer

function without any additional sensor. The MS5803-02BA can be

interfaced to virtually any microcontroller. The communication

protocol is simple, without the need of programming internal

registers in the device. The gel protection and antimagnetic

stainless steel cap allows the use in 100m water resistant

altimeter/compass watches. This new sensor module generation

is based on leading MEMS technology and latest benefits from

MEAS Switzerland proven experience and know-how in high

volume manufacturing of altimeter modules, which have been

widely used for over a decade. The sensing principle employed

leads to very low hysteresis and high stability of both pressure and

temperature signal.
