1.2 Product Description
The KP126 is a miniaturized Absolute Pressure Sensor IC based on the capacitive principle. It is surface
micromachined with a monolithic integrated signal conditioning circuit implemented in BiCMOS standard
technology. Because the KP126 is a high-precision IC for cost-critical solutions, the chip is packaged in a “green”
low-cost SMD housing. The sensor is developed for measurement of barometric air pressure (BAP).
High accuracy and high sensitivity enable the deployment of this device in automotive applications as well as in
consumer applications.
As standard the calibrated transfer function converts a pressure range from 40 kPa to 115 kPa into an analog
output voltage between 0.5 V and 4.5 V. Customized transfer functions and clamping can be realized as well.
