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
Extended Pressure Range: 10 to 2000mbar
I2C and SPI interface (Mode 0, 3)
No external components (Internal oscillator)
Excellent long term stability
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.

RESET SEQUENCE
The Reset sequence shall be sent once after power-on to make sure that the calibration PROM gets loaded into
the internal register. It can be also used to reset the device ROM from an unknown condition
