MEMS Pressure sensor with waterproof

Overview
The S137 SIP (System-in-a-Package) solution comprises of a resistive bridge type pressure sensor and a 24-bit ADC for high resolution and accurate pressure measurements. The fully calibrated pressure and temperature compensated digital output makes the S137 solution simple to use.
The S137 comprises of an internal calibration logic that provides accurate pressure and temperature measurements to the application via I²C interface.
There is no need to separately download internal calibration coefficients and have the host micro-controller conduct complicated compensation calculations.
