Product Description
The KP123 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 KP123 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 consumer applications.
The calibrated transfer function converts a pressure range from 15 kPa to 115 kPa into an analog output voltage between 0.2 V and 4.7 V.
