MPXV7002DPT1

Overview

The MPXV7002DPT1 is an integrated silicon pressure sensor designed for a wide range of applications, particularly those employing a microcontroller or microprocessor with A/D inputs. This piezoresistive transducer combines advanced micromachining techniques, thin-film metallization, and bipolar processing to provide an accurate high-level analog output signal proportional to applied pressure.

Why Choose This Part

This sensor features a small footprint SOP package with dual ports, making it easy to integrate into compact PCB layouts. It is specifically designed for low-pressure ranges from -2 to 2 kPa, offering high sensitivity and an offset precisely calibrated at 2.5V to simplify interfacing with 5V microcontrollers.

Applications

Getting Started

Connect the sensor's analog output to an ADC pin on your microcontroller, ensuring a stable 5V supply for the Vcc pin. Since the output is linear, a simple transfer function can convert the voltage reading back into kPa or mmH2O. Use flexible tubing to connect the dual ports to your pressure source, ensuring no moisture enters the transducer.
