MS5540C

MS5540C Miniature Barometer Module SPECIFICATIONS  10 - 1100 mbar absolute pressure range  6 coefficients for software compensation stored on-chip  Piezoresistive silicon micromachined sensor  Integrated miniature pressure sensor 6.2 x 6.4 mm  16 Bit ADC  3-wire serial interface  1 system clock line (32.768 kHz)  Low voltage and low power consumption The MS5540C is a SMD-hybrid device including a precision piezoresistive pressure sensor and an ADC-Interface IC. It is a miniature version of the MS5534C barometer/altimeter module and provides a 16 Bit data word from a pressure and temperature dependent voltage. MS5540C is a low power, low voltage device with automatic power down (ON/OFF) switching. A 3-wire interface is used for all communications with a micro-controller. Compared to MS5534A the pressure range (measurement down to 10 mbar) has been improved. The MS5540C is fully software compatible to the MS5534C and previous versions of MS5540. In addition, the M...
