This document describes the features and characteristics of the Motorola MPX4080D series pressure sensor. The sensor utilizes advanced micromachining techniques and thin-film metallization to provide an accurate, high-level analog output signal for systems employing microcontrollers or microprocessors.
The MPX4080D is a monolithic silicon piezoresistive pressure sensor designed for microcontroller or microprocessor‑based systems. It features a patented silicon shear‑stress strain gauge, durable epoxy unibody construction, and on‑chip temperature compensation, providing an analog output proportional to pressure.
Key specifications include a pressure range of 0‑80 kPa, supply voltage around 5 Vdc, 3 % maximum error over 0 °C‑85 °C, and an over‑pressure rating of 400 400 kPa. The device is supplied in a basic element package (case 867‑08) with pins for Vout, ground, and VCC.
| Pressure Range | 0 – 80 kPa |
|---|---|
| Supply Voltage | 4.85 – 5.35 Vdc (typical 5.1 V) |
| Supply Current | 7 – 10 mA |
| Maximum Error | 3.0 % over 0 °C‑85 °C |
| Sensitivity | 54 mV/kPa |
| Over‑pressure Rating | 400 400 kPa |
It measures pressures from 0 to 80 kPa.
The sensor operates from 4.85 V to 5.35 Vdc, with a typical value of 5.1 V.
The maximum error is 3.0 % over the temperature range of 0 °C to 85 °C.
It can tolerate an over‑pressure of up to 400 400 kPa.
