NXP Semiconductors MPX2200GP

Overview

MPX2200GP from Freescale Semiconductor is a gauge-pressure silicon piezoresistive sensor with on-chip temperature compensation, delivering 40 mV full-scale output at 10 V supply across 0–200 kPa range, ±0.25% linearity (end-point fit), and <1.0 ms response time. It operates from –40°C to +125°C and is used in medical diagnostics, level detection, and pressure switching where dry-air media compatibility and stable offset (<±1.0 mV) are critical.

For engineers reviewing the MPX2200GP datasheet, MPX2200GP pinout, MPX2200GP application, or MPX2200GP equivalent, this page provides verified package mapping (Case 344B-01), calibrated output behavior, pressure-side identification (port-attached side = P1), and direct alternatives for gauge-pressure sensing in industrial and medical systems.

Technical Context

The MPX2200GP integrates a monolithic silicon diaphragm with laser-trimmed thin-film resistor networks for span and offset calibration. Its ratiometric output scales linearly with supply voltage (10 V typical, up to 16 V max), and internal temperature compensation maintains accuracy over 0°C to +85°C operating range.

It uses a 4-pin unibody chip carrier (Case 344B-01) with dual ports: P1 (positive pressure side, identified by port attachment) and P2 (vacuum reference side). Output impedance (1400–3000 Ω) and input impedance (1300–2500 Ω) support direct interface with instrumentation amplifiers without buffering.

Key Specifications

Pinout & Package

MPX2200GP uses Case 344B-01: 4-pin unibody chip carrier with stainless steel cover, silicone gel isolation, and dual pressure ports. P1 (pressure side) is identified by the port-attached surface; P2 (vacuum reference) is the opposing side.

The following parts are listed as comparable options for similar gauge-pressure sensing applications.

Compared with MPX2200GP, MPX5700GP extends pressure range but increases board area and shifts supply requirements, while MPXV7007DP trades analog simplicity and gauge capability for digital output and ultra-low-range precision - neither is pin-compatible, and both require layout and firmware changes.

The MPX2200GP belongs to Freescale's legacy MPX2200 series of silicon piezoresistive pressure sensors, engineered specifically for high-stability, temperature-compensated gauge-pressure measurement in safety- and reliability-sensitive applications.

FAQ

What is the pressure reference type of the MPX2200GP?

The MPX2200GP is a gauge-pressure sensor: it measures pressure relative to ambient atmospheric pressure, with P2 port sealed to an internal vacuum reference. This configuration enables direct reading of positive pressure applied to the P1 port without external venting, making it ideal for applications like liquid level sensing and medical airflow monitoring where absolute vacuum reference is impractical.

Does the MPX2200GP require external signal conditioning?

The MPX2200GP delivers a raw ratiometric analog output (typically 40 mV full-scale at 10 V supply) and does not include built-in amplification or ADC. Users must implement external signal conditioning - such as an instrumentation amplifier with gain ≥25 and low-offset design - to resolve sub-mV changes. Its 1400–3000 Ω output impedance and ±1.0 mV offset are optimized for this discrete analog front-end approach.

How is the pressure side (P1) identified on the MPX2200GP package?

Per Freescale documentation, the pressure side (P1) of the MPX2200GP is the side with the port attached - visible as a molded opening in the Case 344B-01 package. The opposing side (P2) is the vacuum reference and must remain unobstructed and sealed during assembly. Incorrect orientation results in inverted or null output, so mechanical mounting must align the port-attached surface with the measured pressure source.

What media compatibility limitations apply to the MPX2200GP?

The MPX2200GP is qualified only for dry air as the pressure medium. Exposure to moisture, oils, solvents, or corrosive gases may degrade the silicone gel encapsulant or corrode internal metallization, causing long-term drift or failure. Freescale explicitly states that alternate media require factory consultation - no derating or validation data is provided in the MPX2200GP datasheet for non-dry-air use.

Is the MPX2200GP RoHS-compliant and lead-free?

The MPX2200GP was manufactured prior to Freescale's full RoHS transition (pre-2006), and its datasheet Rev 13 (10/2008) does not declare RoHS compliance or lead-free status. No Pb-free variant (e.g., MPX2200GP* suffix) is documented. For new designs requiring RoHS conformance, engineers should verify current NXP-partnered sourcing or consider modern alternatives like the MP3V5050GV or NCP1855.
