This document is a technical data manual for MPX4080D series piezoresistive transducer, which adopts advanced micromachining technology, thin film metallization and bipolar processing to provide an accurate, high level analog output signal that is proportional to the applied pressure.
The MPX4080D series is a monolithic silicon piezoresistive pressure transducer designed for applications that use a microcontroller or microprocessor with A/D inputs. It offers a high‑accuracy analog output proportional to applied pressure and includes built‑in temperature compensation and a durable epoxy unibody package.
The document lists electrical ratings, mechanical dimensions, pin assignments, and performance parameters such as pressure range, supply voltage, accuracy, and sensitivity. It also includes ordering information, side‑identification for the pressure and vacuum ports, and legal disclaimer statements.
| Pressure range | 0 – 80 kPa (0 – 11.6 psi) |
|---|---|
| Supply voltage (VS) | 4.85 – 5.35 Vdc (typical 5.1 Vdc) |
| Maximum overpressure | 400 kPa |
| Storage temperature | -40°C to +125°C |
| Operating temperature | -40°C to +105°C |
| Maximum error | 3.0% over 0°C to 85°C |
| Sensitivity | 54 mV/kPa |
The sensor can tolerate up to 400 kPa of overpressure.
Pins 4, 5, and 6 are designated as no‑connect and should not be tied to external circuitry.
The typical supply voltage is 5.1 Vdc, with a range from 4.85 Vdc to 5.35 Vdc.
The sensor’s maximum error is 3.0 % over the temperature range of 0 °C to 85 °C.
