Product Details
Company Profile

30-130 Fully Compensated Temperature And Pressure Output Medical Pressure Sensors

CPS121 Accuracy<± 0.3kpa, 30-130 fully compensated temperature and pressure output

Product Description

The CPS121 system-in-a-package (SIP) 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 CPS121 solution simple to use.The CPS121includes internal calibration logic that provides accurate pressure and temperature measurements to the application via the I²C interface.There is no need to separately download internal calibration coefficients and have the host microcontroller perform complicated compensation calculations.
