Barometric Air Pressure Sensors (BAP)

Barometric Air Pressure Sensors (BAP) KP125 The KP125 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 KP125 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. The KP125 has an input pressure range from 40 kPa to 115 kPa. Applied pressure is transferred to an Analog output voltage between 0.5 V and 4.5 V. By Infineon Technologies Corporation
