Overview

The KP236XTMA1 is a high-precision monolithic absolute pressure sensor designed for engine management and industrial applications. It utilizes a micromachined capacitive sensor element and integrates signal conditioning, temperature compensation, and an amplified analog output on a single chip. Its 40kPa to 115kPa range makes it specifically suited for manifold absolute pressure (MAP) or barometric pressure sensing.

Why Choose This Part

The sensor features a high accuracy of +/-2kPa and is fully temperature compensated, ensuring reliable performance across automotive temperature ranges. Its amplified analog output (0.5 V to 4.5 V) eliminates the need for external signal conditioning, simplifying integration with standard 5V microcontroller ADCs.

Applications

Automotive MAP Sensing
Used in engine control units (ECU) to monitor intake manifold absolute pressure for fuel injection timing and air-fuel ratio calculations.
Barometric Pressure Monitoring
Provides accurate atmospheric pressure data for altitude compensation in automotive and industrial control systems.
Industrial Process Control
Monitoring low-pressure pneumatic systems or vacuum lines where absolute pressure measurement is required between 40kPa and 115kPa.

Getting Started

To evaluate this sensor, provide a stable 5V DC supply and interface the analog output pin to an ADC with a high input impedance. Since the package is a surface-mount 8-SMD module, ensure proper soldering techniques for pressure-sensitive components to avoid mechanical stress-induced offsets. Refer to the transfer function in the datasheet to convert the measured voltage back to kPa values.
