Overview
Description
MPX4115AS is an integrated MEMS pressure sensor (absolute/MAP type) from NXP/Freescale. It provides an analog voltage output that is proportional to sensed pressure, designed for 5V systems.
Key points:
- Pressure range: about 0–100 kPa (0–1 bar) absolute.
- Output: DC voltage, roughly 0.2 V at minimum pressure to near the supply rail at full scale; linear and temperature-compensated.
- Supply: typically 5V (works in a 4.5–5.5V window).
- Package: surface-mount (AS suffix), compact footprint; typically three connections (Vcc, GND, Vout) with required bypassing.
- Calibration: factory-calibrated with good linearity and low temperature drift.
- Applications: engine MAP sensors, altitude/pressure sensing, HVAC, weather/industrial sensing.
In short, MPX4115AS is a small, low-drift, analog pressure sensor suitable for automotive MAP sensing and other 0–1 bar absolute pressure applications.
