NXP MPX4115AS Pressure Sensor

The NXP MPX4115AS is a state-of-the-art pressure sensor that provides an analog output signal proportional to the applied pressure. This integrated pressure sensor is designed for a wide range of applications, particularly those employing a microcontroller or microprocessor with A/D inputs. The sensor combines advanced micromachining techniques, thin-film metallization, and bipolar processing to provide an accurate, high-level analog output signal that is proportional to the pressure.

Featuring a pressure range of 15 to 115 kPa, the MPX4115AS delivers an output voltage that is directly proportional to the pressure measured. The sensor operates on a 5V supply voltage and provides a 0.2 to 4.8V output span. This wide range makes it suitable for various applications, including altimeters, barometers, and weather monitoring systems.

The sensor is housed in a small outline package (SOP) that is easy to mount on a printed circuit board. The MPX4115AS is designed for cost-effective, high-volume production, with features that appeal to system designers who demand reliability and accuracy. It is temperature compensated over the -40°C to +125°C range, which ensures stable performance under varying environmental conditions.

The MPX4115AS integrates on-chip, bipolar op-amp circuitry and thin-film resistor networks to provide a high output signal and temperature compensation. The sensor's transfer function is virtually linear, making it easy to integrate with electronic control systems. The precise calibration and temperature compensation reduce the need for in-system calibration, saving time and resources during manufacturing.

NXP's commitment to quality ensures that the MPX4115AS meets the stringent requirements for automotive applications. It is also versatile enough to be used in medical devices, industrial controls, and consumer products. The MPX4115AS is a reliable choice for designers looking to measure pressure with high accuracy and robustness.
