NXP Semiconductors MP3V7007GP

Overview

MP3V7007GP from Freescale Semiconductor is a monolithic silicon piezoresistive pressure sensor with on-chip signal conditioning, temperature compensation, and factory calibration. It delivers a ratiometric analog output (0.2–2.8 V) over a ±7 kPa gauge pressure range at 3.0 V supply, with ±5.0% full-scale accuracy across 0°C to 85°C and operating temperature support from –40°C to +125°C. It is used in respiratory systems, HVAC controls, and hospital bed pressure monitoring.

For engineers reviewing the MP3V7007GP datasheet, MP3V7007GP pinout, MP3V7007GP application, or MP3V7007GP equivalent, this page provides verified technical context, package mapping to Case 1369-01, confirmed pin functions, real-world use scenarios, and two validated alternative transducers for gauge-pressure sensing in microcontroller-based systems.

Technical Context

The MP3V7007GP integrates a patented silicon shear-stress strain gauge with thin-film metallization and bipolar processing on a single die. Its signal chain includes two gain stages, temperature compensation circuitry, and ground reference shift logic - all monolithically embedded to deliver stable analog output without external calibration.

It operates as a ratiometric device: output voltage scales linearly with supply voltage (2.7–3.3 V), following V_out = V_S × (0.057 × P + 0.5), where P is differential pressure in kPa. The sensor requires the decoupling network shown in Figure 3 (1.0 μF + 0.01 μF + 470 pF) to meet specified accuracy and response time of ≤1.0 ms.

Key Specifications

Pinout & Package

MP3V7007GP uses Case 1369-01: an 8-pin thermoplastic (PPS) surface-mount small outline package with 2.54 mm pitch, 7.11–7.62 mm width, and port-on-P1-side identification. Pins 1, 5, 6, 7, and 8 are no-connects; active terminals are GND, V_OUT, V_S, and –V_OUT (differential configuration not enabled in gauge variant).

FAQ

What is the pressure type and range supported by the MP3V7007GP?

The MP3V7007GP is a gauge pressure sensor with a range of ±7 kPa (–1 to +1 psi). It measures pressure relative to ambient atmospheric pressure using a single port (P1 side identified by port attachment per Case 1369-01 marking). The device outputs 0.2 V at –7 kPa and 2.8 V at +7 kPa when supplied with 3.0 V, maintaining ratiometric behavior across its 2.7–3.3 V supply range. This range is optimized for low-pressure medical and environmental sensing.

Does the MP3V7007GP require external calibration or compensation circuitry?

No, the MP3V7007GP does not require external calibration or temperature compensation circuitry. It integrates on-chip signal conditioning, factory calibration, and temperature compensation over –40°C to +125°C. The output follows the nominal transfer function V_out = V_S × (0.057 × P + 0.5), and all error contributors (linearity, hysteresis, TcSpan, TcOffset) are included in its ±5.0% VFSS accuracy specification. Only basic power decoupling (1.0 μF + 0.01 μF + 470 pF) is required per Figure 3.

What is the correct pin configuration and terminal assignment for MP3V7007GP?

The MP3V7007GP uses an 8-pin Case 1369-01 package with active terminals on pins 1 (GND), 2 (V_OUT), 3 (V_S), and 4 (–V_OUT). Pins 5–8 are no-connects. Pin 1 is GND, pin 2 is analog output, pin 3 is supply input, and pin 4 is the differential complement - unused in gauge mode and typically left floating or grounded per layout guidelines. The P1 (pressure) side is identified by the port location, not marking.

Can MP3V7007GP be used with a 5 V microcontroller ADC?

The MP3V7007GP is rated for 2.7–3.3 V supply and outputs 0.2–2.8 V - it is not designed for direct 5 V operation. Using it with a 5 V microcontroller ADC requires either a 3.0 V LDO regulator for V_S and reference, or a precision resistive divider on V_OUT with proper buffering. Its ratiometric nature means optimal accuracy is achieved when the ADC reference matches V_S, so pairing with a 3.0 V ADC reference is strongly recommended for MP3V7007GP.

What media compatibility considerations apply to MP3V7007GP?

The MP3V7007GP is qualified for dry air as the pressure medium. Its fluorosilicone gel coating protects the die but does not guarantee compatibility with liquids, oils, or aggressive gases. Freescale explicitly states that non-dry-air media may degrade long-term reliability or cause performance shifts. For applications involving moisture, condensation, or chemical exposure, validation with the manufacturer or selection of a media-rated variant (e.g., stainless steel port versions) is required before deployment. MP3V7007GP is not rated for direct contact with bodily fluids or sterilants.
