DESCRIPTION

The MS5803-xxBA is a new generation of high resolution sensors with SPI & I²C interface. The sensor module includes a high linearity pressure sensor with an ultra low power 24 bit ADC with internal factory calibrated coefficients. It provides precise digital 24 bit pressure and temperature values 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 an additional sensor. Gel protection and an antimagnetic stainless steel cap allow the use in 100m waterproof altimeter/compass watches.

The MS5803 is available in the following pressure ranges:

MS5803-01BA: 10-1300mbar
MS5803-02BA: 300-2000mbar
MS5803-05BA: 0-6bar
MS5803-14BA: 0-14bar
MS5803-30BA: 0-30bar

*Modules are pressure sensors, whose output signals have to be calculated by an external microprocessor.

As accessory available:
  • Sample boards for use with the USB Development kit for quick evaluation of the pressure sensors.
  • Light and dust protection caps with or without connector.
