Transducers

digital barometerpressure sensorI2C24-bit ADClow powerLGA

CPM121 is a factory-calibrated digital barometer with compensated pressure and temperature outputs over I2C.

Best for

  • Low-power pressure measurement
  • Portable barometers and altimeters
  • Weather and GPS equipment

Avoid if

  • A different I2C address is required
  • The application requires a package height that has not been verified
  • Lifecycle or availability guarantees are required

Check before use

  • Electrical supply and I2C pull-up compatibility
  • Measurement timing and data conversion format
  • PCB footprint and package height
