NXP Semiconductors MPX5700GP1

Overview

MPX5700GP1 from Freescale Semiconductor is a gauge-pressure silicon piezoresistive transducer with on-chip signal conditioning, temperature compensation, and factory calibration. It delivers a ratiometric 0.2–4.7 V analog output over 0–700 kPa (0–101.5 psi), operates from 4.75–5.25 V supply, draws ≤10 mA, and maintains ±2.5% full-scale accuracy across –40°C to +125°C. It is used in microcontroller-based HVAC pressure monitoring systems requiring stable, calibrated analog feedback.

For engineers reviewing the MPX5700GP1 datasheet, MPX5700GP1 pinout, MPX5700GP1 application, or MPX5700GP1 equivalent, key selection criteria include its 700 kPa gauge pressure range, Case 867B-04 unibody epoxy package with 90° lead form, 1.0 ms response time, and compatibility with standard A/D interfaces in embedded industrial control designs.

Technical Context

The MPX5700GP1 integrates a micromachined silicon diaphragm with thin-film piezoresistors, bipolar signal conditioning circuitry, and two-stage gain amplification. Its transfer function is Vout = VS × (0.0012858 × P + 0.04), where VS = 5.0 Vdc and P is pressure in kPa.

It features internal temperature compensation for offset and span drift, fluorosilicone gel isolation of the die, and a stainless steel cap protecting the P1 (positive pressure) side. Pins 4, 5, and 6 are no-connects per the schematic and package drawings.

FAQ

What pressure media is compatible with the MPX5700GP1?

The MPX5700GP1 is qualified for dry air as the pressure medium. Use of other media-including moisture, oils, or corrosive gases-may degrade long-term reliability or cause permanent damage. Freescale explicitly states that fluorosilicone gel isolation is optimized for dry air; consult NXP's factory for media compatibility testing before deploying MPX5700GP1 in non-air applications.

Does the MPX5700GP1 require external calibration after soldering?

No, the MPX5700GP1 does not require external calibration after soldering. It ships fully temperature-compensated and factory-calibrated over 0–85°C, with zero pressure offset and full-scale output pre-trimmed. The ±2.5% accuracy specification includes all contributions-linearity, thermal hysteresis, and TcSpan-so MPX5700GP1 can be deployed directly into production without post-mount calibration.

What is the significance of the "90 degree lead form" in MPX5700GP1?

The "90 degree lead form" means the leads are bent perpendicular to the package body, enabling vertical insertion into PCBs with minimal footprint. This differs from the straight-lead MPX5700GP and allows tighter mechanical integration in space-constrained enclosures-such as HVAC control panels or automotive junction boxes-where horizontal lead clearance is limited.

Can the MPX5700GP1 operate outside its specified 0–85°C accuracy range?

Yes, the MPX5700GP1 functions across –40°C to +125°C, but its ±2.5% accuracy guarantee applies only from 0°C to 85°C. Outside this range, offset and span drift increase beyond datasheet limits; for example, TcOffset rises significantly below 0°C. System designers must validate performance at target operating temperatures if using MPX5700GP1 beyond 0–85°C.

Why are pins 4, 5, and 6 labeled as no-connects on the MPX5700GP1?

Pins 4 (V1), 5 (V2), and 6 (VEX) are internally unconnected in the MPX5700GP1 die and package. They exist for mechanical symmetry and legacy pin compatibility across the MPX5700 family but carry no electrical function. Per Freescale's schematic and package documentation, these pins must be left floating or tied to GND-never driven-to avoid unintended coupling or ESD paths affecting VOUT stability.
