De
TheMS5540Cis a SMD-hybrid device including a precision piezoresistive pressure sensor and an ADC Interface IC. It is a miniature version of theMS5534Cbarometer/altimeter module and provides a 16 Bit data word from a pressure and temperature dependent voltage.MS5540Cis a low power, low voltage device with automatic power down (ON/OFF) switching. A 3-wire interface is used for all communications with a microcontroller. Compared to MS5534A the pressure range (measurement down to 10 mbar) has been improved. TheMS5540Cis fully software compatible to theMS5534Cand previous versions of MS5540. In addition, theMS5540Cis from its outer dimensions compatible to the MS54XX series of pressure sensors. Compared to the previous version the ESD sensitivity level has been improved to 4 kV on all pins. The gel protection of the sensor provides a water protection sufficient for 100 m waterproof watches without any additional protection
