MS5540B

MS5540B (RoHS*) MINIATURE BAROMETER MODULE 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 15 Bit ADC 3-wire serial interface 1 system clock line (32.768 kHz) Low voltage and low power consumption RoHS-compatible & Pb-free* DESCRIPTION The MS5540B is a SMD-hybrid device including a precision piezoresistive pressure sensor and an ADCInterface IC. It is a miniature version of the MS5534B barometer/altimeter module and provides a 16 Bit data word from a pressure and temperature dependent voltage. MS5540B 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 microcontroller. Compared to MS5534A the pressure range (measurement down to 10 mbar) has been improved. Other improvements concern the ESD sensitivity, current consumption an...
