Product details
Overview
MPXV5100GP from NXP Semiconductors is a piezoresistive silicon pressure sensor configured for gauge pressure measurement over 0 to 100 kPa, delivering a ratiometric analog output (4.5–4.8 V at full scale with 5 V supply), ±2.5% accuracy over 0–85 °C, and 1 ms response time. It integrates on-chip temperature compensation and is designed for direct interface with microcontroller A/D inputs in medical monitoring and industrial control systems.
For engineers reviewing the MPXV5100GP datasheet, MPXV5100GP pinout, MPXV5100GP application, or MPXV5100GP equivalent, key selection factors include its side-port small-outline package (98ASA99303D), 8-pin configuration with only 4 active terminals, gauge pressure sensing architecture, and compatibility with dry air media in sealed or vented systems.
Technical Context
The MPXV5100GP implements a monolithic silicon shear-stress strain gauge with thin-film metallization and bipolar signal conditioning. Its two-stage gain architecture includes integrated temperature compensation circuitry that corrects offset and span drift across 0–85 °C, enabling stable operation without external calibration components.
It operates ratiometrically with a 4.75–5.25 V supply, producing an output voltage defined by VOUT = VS × (0.009 × P + 0.04), where P is pressure in kPa. The device uses fluorosilicone gel encapsulation to isolate the die while transmitting pressure to the diaphragm, and requires no external decoupling beyond a 1.0 μF bulk capacitor and 0.01 μF ceramic capacitor per the recommended power supply filtering circuit.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0 to 100 kPa gauge - supports standard atmospheric differential sensing with 15 kPa margin before saturation. |
| Output Voltage (Full Scale) | 4.587–4.813 V at VS = 5.0 V - enables direct connection to 5 V ADC references without level-shifting. |
| Accuracy | ±2.5% of full-scale span (VFSS) - includes linearity, temperature hysteresis, pressure hysteresis, TcSpan, and TcOffset contributions. |
| Response Time | 1.0 ms (10% to 90%) - suitable for dynamic pressure monitoring in pump control and respiratory flow applications. |
| Supply Voltage | 4.75–5.25 VDC - ratiometric operation ensures output scaling tracks supply variations, simplifying system-level calibration. |
| Operating Temperature | −40 to +125 °C - validated for industrial environments; specified accuracy applies over 0–85 °C ambient range. |
| Sensitivity | 45 mV/kPa - yields ~4.5 V output swing across full range, providing high signal-to-noise ratio for 12-bit ADCs. |
Pinout & Package
MPXV5100GP uses the 8-lead side-port small outline package (case 98ASA99303D), measuring 10.54 × 10.54 × 12.70 mm, with port located on the long side of the body. Pins 1, 5–8 are internal connections and must remain unconnected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | DNC | Internal lead frame connection - no external connection permitted; floating or grounded violates specification. |
| 2 | VS | Positive supply input - requires local 1.0 μF + 0.01 μF decoupling to maintain ratiometric stability and noise immunity. |
| 3 | GND | Analog ground reference - must be tied to system AGND with low-impedance path to minimize offset error. |
| 4 | VOUT | Analog output - delivers buffered, temperature-compensated voltage proportional to applied gauge pressure. |
| 5–8 | DNC | Internal device connections - no routing, soldering, or PCB trace attachment allowed per datasheet Figure 4. |
Key Features
| Feature | Design Value |
|---|---|
| Piezoresistive silicon shear-stress gauge | Monolithic construction eliminates bond wire stress-induced drift, improving long-term zero-point stability. |
| On-chip temperature compensation | Corrects both offset and full-scale span over 0–85 °C without external components or firmware calibration. |
| Ratiometric output | Output scales linearly with supply voltage, removing need for precision voltage references in cost-sensitive systems. |
| Fluorosilicone gel isolation | Protects die and wire bonds from moisture and particulates while maintaining mechanical coupling to pressure port. |
| Side-port small-outline package | Enables compact PCB layout with horizontal pressure access-ideal for space-constrained medical and appliance designs. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar gauge pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPX5100GP | 6-lead unibody package (98ASB42796B); single-port; wider footprint; higher thermal mass. | Preferred for through-hole prototyping or legacy board designs requiring larger mounting area. | Select MPX5100GP only if board layout accommodates 6-pin unibody form factor and vertical port orientation is acceptable. |
| MPXV5100GC6U | Same 8-lead SO package (98ASB17757C); identical pinout and electrical specs; differs only in tape-and-reel packaging (rail vs tray). | No functional difference - GC6U is functionally identical but supplied in rail format for automated placement. | Choose MPXV5100GC6U for high-volume SMT production requiring reel-fed pick-and-place; otherwise MPXV5100GP is drop-in compatible. |
Compared with MPX5100GP, the MPXV5100GP offers superior board-space efficiency and faster thermal response due to its smaller 8-lead SO package, while MPXV5100GC6U provides identical performance in a different packaging format optimized for automated assembly - neither requires PCB redesign when substituting for MPXV5100GP.

FAQ
What pressure type does the MPXV5100GP measure?
The MPXV5100GP is a gauge pressure sensor, meaning it measures pressure relative to ambient atmospheric pressure. Its port is vented to atmosphere, and it delivers an output voltage proportional to the differential between applied pressure and local barometric pressure. This configuration is confirmed in the ordering information table and block diagram for MPXV5100GP in the MPX5100 datasheet Rev. 14.
What is the correct supply voltage range for stable operation of the MPXV5100GP?
The MPXV5100GP operates reliably within a supply voltage range of 4.75 V to 5.25 V DC. Operation outside this window risks violating maximum ratings and degrading accuracy or response time. The device is ratiometric, so output scales linearly with VS - maintaining tight regulation within this band ensures consistent full-scale span and offset performance across temperature.
Can the MPXV5100GP be used with media other than dry air?
No - the MPXV5100GP is qualified and characterized exclusively for use with dry air as the pressure medium. Exposure to liquids, oils, solvents, or corrosive gases may degrade fluorosilicone gel integrity, damage wire bonds, or cause long-term drift. NXP explicitly states in Section 3 of the MPX5100 datasheet that alternative media require factory consultation prior to deployment.
How many pins on the MPXV5100GP are electrically active, and which ones must remain unconnected?
The MPXV5100GP has eight physical leads, but only four are electrically active: Pin 2 (VS), Pin 3 (GND), Pin 4 (VOUT), and Pins 1, 5–8 are designated DNC (Do Not Connect). Connecting any DNC pin to ground, power, or signal traces violates the datasheet specification and may impair accuracy or cause permanent damage.
What is the warm-up time specification for the MPXV5100GP before achieving full accuracy?
The MPXV5100GP requires a maximum warm-up time of 20 ms after power-on and pressure stabilization to meet its full-specified output voltage accuracy. This value is defined in Table 4 of the MPX5100 datasheet under "Warm-up time" and reflects the time needed for internal thermal equilibrium and amplifier settling - critical for applications requiring rapid startup like portable medical devices.
