Digital Output Pressure Sensor CPS137 Operating Temperature Range: -40°C To +85° Factory Calibrated Pressure And Temperature Sensor
The CPS137SIP (System-in-a-Package) solution comprises of aresistive 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 CPS137 solution simple to use.The CPS137comprises 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.
