MS5536C Datasheet, PDF (1/17 Pages) Intersema Sensoric SA – SMD Gage Pressure MODULE

MS5536C (RoHS*) SMD Gage Pressure MODULE
• Pressure range -400 to 1000 mbar
(Optional -1000 to 400 mbar)
• 0.1 mbar Resolution
• Factory Calibrated (coefficients for
software compensation stored on-
chip)
• 3-wire serial interface
• Low voltage / low power
DESCRIPTION
MS5536C is a family of high-resolution factory calibrated pressure sensors. The devices include a piezoresistive
pressure sensor and an ADC-Interface 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.
