NXP Semiconductors MPX2200D

Overview

MPX2200D from Freescale Semiconductor is a silicon piezoresistive differential pressure sensor with on-chip temperature compensation, ±0.25% linearity (end-point fit), 0–200 kPa full-scale range, and 40 mV typical full-scale output at 10 V supply. It serves as a ratiometric analog transducer in closed-loop pressure control systems for medical diagnostics and industrial automation.

For engineers reviewing the MPX2200D datasheet, MPX2200D pinout, MPX2200D application, or MPX2200D equivalent, this device requires attention to port-side identification (P1 = stainless steel cap side), unibody Case 344-15 packaging, excitation voltage limits (10 V typical, up to 16 V), and differential pressure media compatibility (dry air recommended).

Technical Context

The MPX2200D integrates a monolithic silicon diaphragm with laser-trimmed piezoresistive strain gauges and thin-film resistor networks for span/offset calibration and temperature compensation across –40°C to +125°C. Its ratiometric output scales linearly with supply voltage and applied differential pressure (P1 > P2).

It operates with fixed 4-pin unibody package pinout (GND, +VOUT, VS, –VOUT), delivers <1.0 ms response time (10–90%), and maintains ±0.1%VFSS pressure hysteresis over 0–200 kPa - enabling high-repeatability sensing without external signal conditioning in low-power embedded systems.

Key Specifications

Pinout & Package

MPX2200D uses the unibody Case 344-15 package: 4-pin, surface-mountable ceramic carrier with stainless steel cap on the P1 (pressure) side and silicone gel isolation of die/wire bonds. Dimensions: 15.11–16.00 mm × 13.06–13.56 mm × 5.08–5.59 mm (L × W × H).

Equivalent & Alternatives

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

Compared with MPX2200D, MPXV7025DP offers digital convenience but sacrifices pressure range and analog flexibility, while SDX200D4 matches the 200 kPa range and package but lacks on-chip temperature compensation and has looser linearity - making MPX2200D preferable for high-accuracy, wide-temperature embedded systems.

Manufacturer

Freescale Semiconductor (now part of NXP Semiconductors) was a leading designer of analog and mixed-signal sensors, microcontrollers, and RF solutions for automotive, industrial, and medical markets.

The MPX2200 series was developed specifically for high-accuracy, temperature-stable differential pressure measurement in safety-critical and portable equipment - emphasizing factory-calibrated linearity, robust packaging, and dry-air media compatibility.

FAQ

What is the correct pressure port orientation for MPX2200D?

The MPX2200D has two ports: P1 (pressure side) and P2 (vacuum side). Per Freescale documentation, the P1 side is identified by the stainless steel cap - this must face the higher-pressure source. Applying pressure to P2 instead may cause irreversible damage or invalid output. Always verify port orientation using the marking and cap before installation in any MPX2200D-based system.

Does MPX2200D require external amplification to interface with a 3.3 V microcontroller ADC?

MPX2200D outputs 38.5–41.5 mV at full scale with 10 V excitation, yielding ~12.5-bit effective resolution when digitized by a 3.3 V, 12-bit ADC. While functional without amplification, gain stages (e.g., instrumentation amplifier) are recommended to maximize SNR and mitigate noise in electrically noisy environments. The MPX2200D itself contains no internal amplification.

Is MPX2200D compatible with fluids other than dry air?

No - Freescale explicitly states that MPX2200D operating characteristics and reliability validation are based solely on dry air as the pressure medium. Exposure to moisture, oils, or corrosive gases may degrade silicone gel encapsulation, alter diaphragm response, or cause long-term drift. For non-dry-air media, consult NXP's application engineering team before deploying MPX2200D in production.

What is the warm-up time specification for MPX2200D?

The MPX2200D warm-up time is specified as ≤20 ms - defined as the time required after pressure stabilization for the output voltage to meet its final specified value. This fast settling supports high-speed sampling in dynamic pressure applications such as robotic actuation feedback or rapid pressure switching circuits using the MPX2200D.

Can MPX2200D be used in absolute pressure mode?

No - MPX2200D is a differential pressure sensor only. It requires both P1 and P2 ports to be connected: P1 to the measured pressure source and P2 to either atmospheric reference (gauge mode) or vacuum reference (differential mode). For absolute pressure measurement, use MPX2200A (absolute variant) or MPX2200AP - these contain sealed vacuum references and distinct case markings.
