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.
