Low Pressure Module MS5537

DESCRIPTION

MS5537 is a family of high resolution factory calibrated pressure sensors. The leaded hybrids are compatible with standard PCB assembly technologies. The devices include a piezoresistive pressure sensor and a mixed signal IC. The 3-wire serial interface ensures simple communication with any microcontroller. The devices provide digital pressure and temperature information as 16-Bit data word each. In addition 64-Bit of individually calibrated compensation coefficients are stored allowing for a highly accurate software compensation of process spread and temperature effects.

The devices have a very low standby current and automatically enter power down mode after each conversion. The optimum compromise of refresh rate and average current consumption can be defined by the application software.

The sensor MS5537 is available in the pressure range 0 to 300 mm H₂O.
