NXP Semiconductors MPX2100GVP

Overview

MPX2100GVP from Freescale Semiconductor is a gauge-mode silicon piezoresistive pressure sensor with on-chip temperature compensation and laser-trimmed calibration, delivering 40 mV full-scale output at 10 V supply across 0–100 kPa range, ±0.25% linearity (end-point method), and 1 ms response time for industrial pressure monitoring in pump controllers and medical diagnostics.

For engineers reviewing the MPX2100GVP datasheet, MPX2100GVP pinout, MPX2100GVP application, or MPX2100GVP equivalent, this page provides verified technical context, package mapping to Case 344D-01, confirmed pin functions, real-world use value in vacuum-referenced systems, and two validated alternative parts with documented functional differences.

Technical Context

The MPX2100GVP integrates a monolithic silicon diaphragm with embedded strain gauges and thin-film resistor networks for direct voltage output proportional to applied differential pressure. Its ratiometric architecture ensures output scaling with supply voltage, and on-chip circuitry delivers temperature compensation over 0°C to +85°C.

As a gauge-pressure sensor, MPX2100GVP features a stainless steel cap on the Pressure (P1) side and an open port on the Vacuum (P2) side, enabling measurement relative to ambient atmospheric pressure. It operates with 6.0 mA supply current and exhibits ±0.1%VFSS pressure hysteresis and ±0.5%VFSS offset stability after 1000-hour stress testing.

Key Specifications

Pinout & Package

MPX2100GVP uses the unibody Case 344D-01 package - a 4-pin, surface-mountable ceramic carrier with stainless steel cap on the P1 side and ported P2 side. Dimensions: 29.08–29.85 mm × 17.40–18.16 mm × 7.75–8.26 mm (L×W×H).

Manufacturer

Freescale Semiconductor (now part of NXP Semiconductors) was a leading designer of embedded processors and analog sensors, known for automotive-grade reliability and industrial signal-conditioning expertise.

The MPX2100 series was developed specifically for high-accuracy, temperature-stable pressure measurement in harsh environments - targeting applications where long-term drift, thermal error, and mechanical robustness are critical design constraints.

FAQ

What is the pressure type and reference configuration of the MPX2100GVP?

The MPX2100GVP is a gauge-pressure sensor with a stainless steel cap on the Pressure (P1) side and an open port on the Vacuum (P2) side, meaning it measures pressure relative to ambient atmospheric pressure. This configuration is confirmed in the Freescale MPX2100 Rev 10 datasheet under the "PRESSURE (P1)/VACUUM (P2) SIDE IDENTIFICATION TABLE", which explicitly lists MPX2100GVP with Case 344D and identifies the stainless steel cap as the P1 side. The MPX2100GVP does not require external vacuum reference.

What are the exact pin functions and recommended layout practices for MPX2100GVP?

The MPX2100GVP uses Style 1 pinout: Pin 1 = GND, Pin 2 = +VOUT, Pin 3 = VS, Pin 4 = −VOUT. Layout best practices include routing differential output traces (Pins 2 and 4) as matched-length, tightly coupled pairs; placing a 0.1 µF ceramic decoupling capacitor between Pin 3 (VS) and Pin 1 (GND); and avoiding thermal vias under the stainless steel cap to preserve temperature compensation integrity. These guidelines derive directly from Freescale's package drawings and application notes for Case 344D-01.

Does MPX2100GVP require external signal conditioning, and what is its output format?

Yes, MPX2100GVP outputs a raw, differential, ratiometric voltage (typically 40 mV full-scale at 10 V supply) that requires external instrumentation amplification and ADC conversion. It does not include internal signal conditioning - unlike later-generation parts such as MPX5100GP. The output is strictly analog, unbuffered, and designed for integration into custom analog front-ends where gain, offset, and filtering are application-specific. This is specified in the "Operating Characteristics" table and Figure 1 schematic of the MPX2100 Rev 10 datasheet.

What is the maximum pressure rating and overpressure survivability of MPX2100GVP?

The MPX2100GVP has a maximum rated pressure of 400 kPa (Table 2, Maximum Ratings), which is four times its full-scale range of 0–100 kPa. This overpressure rating ensures mechanical survival during transient spikes in pump or compressor systems. However, operation above 100 kPa invalidates accuracy specifications, and exposure beyond 400 kPa may cause permanent damage per Freescale's caution in Table 2 footnote 1. The sensor is qualified for dry air only; other media may degrade long-term performance.

How does temperature compensation work in MPX2100GVP, and what is its effective range?

MPX2100GVP implements on-chip thin-film resistor networks that actively compensate for temperature-induced drift in both full-scale span (TCVFSS ≤ ±1.0%VFSS) and offset (TCVoff ≤ ±1.0 mV) across 0°C to +85°C - as measured relative to 25°C baseline. This compensation is factory-laser-trimmed and requires no external components. While the device operates from −40°C to +125°C, the published compensation performance (linearity, hysteresis, TCVFSS) is guaranteed only within the 0°C to +85°C range per Table 1 and "Temperature Compensated Over 0°C to +85°C" feature bullet.
