NXP Semiconductors MPX2202GP

Overview

MPX2202GP from NXP Semiconductors (formerly Freescale) is a gauge-pressure silicon piezoresistive sensor with on-chip temperature compensation, delivering a ratiometric 40 mV full-scale output at 10 V supply across 0–200 kPa range, used in medical diagnostics and pressure switching systems requiring stable analog transduction.

For engineers reviewing the MPX2202GP datasheet, MPX2202GP pinout, MPX2202GP application, or MPX2202GP equivalent, this page provides verified technical context, calibrated performance parameters, unibody package details, real-world use cases, and validated alternative options for industrial and medical pressure sensing designs.

Technical Context

The MPX2202GP integrates a monolithic silicon diaphragm with laser-trimmed strain gauges and thin-film resistor networks for precision span and offset calibration. It operates as a gauge-pressure device with P1 (pressure port) and P2 (vacuum reference port), requiring differential excitation between VS and GND.

Its ratiometric output scales linearly with supply voltage (10 V typical), exhibits ±0.4%VFSS linearity (end-point method), and maintains offset stability of ±0.5%VFSS after 1000-hour pulsed pressure/temperature cycling - all specified over –40°C to +125°C operating temperature range.

Key Specifications

Pinout & Package

MPX2202GP uses Case 344B-01 unibody ceramic package with 4-pin lead frame and integrated stainless steel port for P1 side identification. Port attachment defines the pressure (P1) side; vacuum (P2) side is sealed internally.

FAQ

What is the pressure type supported by the MPX2202GP?

The MPX2202GP is a gauge-pressure sensor with two ports: P1 (positive pressure port, identified by attached stainless steel port) and P2 (internal vacuum reference). It measures pressure relative to ambient atmospheric pressure, making it ideal for applications like level sensing and pneumatic control where absolute vacuum reference is unnecessary. The MPX2202GP does not support absolute or differential configurations - those require MPX2202A or MPX2202DP variants respectively.

What is the recommended supply voltage for MPX2202GP and how does it affect output?

The MPX2202GP is specified for 10 V DC typical supply, with an operating range of up to 16 V DC. Its output is ratiometric: the full-scale voltage scales linearly with supply voltage (e.g., 40 mV at 10 V becomes ~20 mV at 5 V). This allows direct interfacing with supply-referenced ADCs and simplifies system-level voltage regulation, but requires stable excitation to maintain measurement accuracy - ripple or drift on VS directly impacts output fidelity.

How is temperature compensation implemented in MPX2202GP?

The MPX2202GP incorporates on-chip thin-film resistor networks laser-trimmed during manufacturing to compensate for temperature-induced span and offset drift. This achieves ±2.0%VFSS full-scale temperature coefficient and ±1.0 mV offset coefficient over –40°C to +125°C, eliminating the need for external thermistors or digital correction algorithms. Compensation is effective across the full operating range and validated per Freescale's internal qualification tests including temperature cycling and hysteresis evaluation.

What are the key mechanical features of the MPX2202GP package?

The MPX2202GP uses Case 344B-01 - a unibody ceramic package with integrated stainless steel pressure port on the P1 side. The package includes silicone gel encapsulation protecting wire bonds and die surface while transmitting pressure to the silicon diaphragm. Dimensions are 1.175" × 0.715" × 0.325", with 4-pin lead frame and seating plane defined per ANSI Y14.5M. Port orientation and marking follow Freescale's P1/P2 identification table, ensuring correct installation in pressurized systems.

Can MPX2202GP be used with single-ended ADC inputs?

Yes, MPX2202GP can interface with single-ended ADCs by referencing –VOUT to GND and reading +VOUT as the active signal. However, its differential output (between +VOUT and –VOUT) provides better noise rejection and common-mode immunity. For optimal performance, a low-input-bias-current instrumentation amplifier with gain ≥25 is recommended to resolve the 40 mV full-scale signal into usable 1–3 V range for 12-bit+ ADCs, especially in electrically noisy environments like motor drives or medical equipment.
