Product details
Overview
KP226K2809XTMA1 from Infineon Technologies is a monolithic silicon pressure sensor IC for absolute pressure measurement in automotive and industrial applications, featuring a calibrated output of 0.5–4.5 V over 0–2.8 bar range, ±1.5% full-scale accuracy, and operation from -40°C to +125°C ambient temperature.
For engineers reviewing the KP226K2809XTMA1 datasheet, KP226K2809XTMA1 pinout, KP226K2809XTMA1 application, or KP226K2809XTMA1 equivalent, this device serves as a direct-fit analog absolute pressure transducer with integrated signal conditioning, rail-to-rail output, and AEC-Q100 Grade 1 qualification for engine manifold, brake vacuum, and turbocharger boost sensing.
Technical Context
The KP226K2809XTMA1 integrates a piezoresistive MEMS pressure sensing element with a precision analog signal conditioning ASIC on a single die. It delivers ratiometric analog output referenced to supply voltage (VSUP), supports 4.5–5.5 V supply, and includes built-in ESD protection (>2 kV HBM) and electromagnetic compatibility features per ISO 11452-2/4.
Its architecture provides factory-trimmed offset and span compensation across temperature, enabling stable output without external calibration. The device uses a proprietary DSOF-8 (Dual Small Outline Flat) package with exposed die pad for thermal performance and mechanical stress isolation in high-vibration environments.
