DESCRIPTION
MS5536 is a family of high-resolution factory calibrated pressure sensors. 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.
