Absolute Pressure Sensor
High accuracy and small size absolute
pressure sensor with low current con-
sumption
• Measure absolute pressure and temperature with high accuracy.
• Built in low noise 24 bits ADC.
• Digital control and output via I2C interface
• Automatically power down non working circuit to minimize current
consumption
• Individual calibration parameters stored in OTP *.
* One Time Programmable Non Volatile Memory
RoHS compliant
Application Example
• Smart Phone
• Activity monitor
• Wearable device
