Overview

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.
