Product Description
The KP234 is a miniaturized Analog Barometric Air Pressure Sensor IC based on a capacitive principle. It is surface micromachined with a monolithic integrated signal conditioning circuit implemented in BiCMOS technology.
The sensor converts a pressure into an analog output signal. The calibrated transfer function converts a pressure range of 40 kPa to 115 kPa into a voltage range of 1.33 V to 4.70 V.

FEATUREs
Following features are supported by the KP234:
• High precision pressure sensing (± 1.5 kPa)
• Ratiometric analog output
• Large temperature range (-40 °C to 125 °C)
• Broken wire detection
• “Green” 8 pin SMD housing
• Automotive qualified

Target Applications
The KP234 is defined for use in following target applications:
• Automotive applications (barometric air pressure measurement)
• Industrial control
• Consumer applications
• Medical applications
• Weather stations
• Altimeters
