MPX4115A

Pressure Sensors Transducers Overview

The MPX4115A is an integrated silicon pressure sensor designed for absolute pressure measurement. It features a sensing range of 15 kPa to 115 kPa (2.18 PSI to 16.68 PSI) with an analog voltage output spanning 0.2 V to 4.8 V. The device operates on a supply voltage of 4.85 V to 5.35 V and includes integrated temperature compensation. It offers high precision with an accuracy of ±1.5% and withstands maximum pressures up to 400 kPa (58.02 PSI). The sensor supports a wide operating temperature range from -40°C to 125°C and utilizes an 8-SMD, gull-wing package with a top port.
