MPX4200A Descripción general
A MAP sensor is a piezoresistive silicon transducer that converts an applied absolute pressure into a strain-gauge bridge resistance change; the on-chip ASIC then amplifies, temperature-compensates, and normalizes that bridge signal into a single-ended analog voltage the ECU's ADC can read directly. It sits hierarchically between bare strain-gauge elements and full ECU front-ends, and within the broader sensor category it is one of the most common automotive-grade pressure sensors, alongside gauge and differential variants. Because the output is ratiometric to VCC, any drift in supply voltage scales both the reference and the output together, simplifying ECU software calibration.
Key features include a 0.3 V to 4.9 V ratiometric analog output (4.65 V nominal full-scale at 200 kPa), 1.5 % maximum pressure error over 0 °C to +85 °C, a -40 °C to +125
operating range, and integrated EMC protection on the supply and output pins. The on-chip bipolar signal conditioner uses a thin-film resistor network laser-trimmed at production to remove offset and span errors, which is why no external calibration components are required. Through-hole 6-SIP mounting keeps the pressure port isolated from the PCB, allowing the manifold to be sealed with an O-ring without contaminating the electronics.
Typical applications include turbo-boost engine control, automotive MAP sensing, industrial pneumatic pressure monitoring, barometric correction for engine management, and altitude-compensation in motorcycle and small-engine ECUs. It is also used as a general-purpose calibrated absolute pressure transducer where a clean analog output is preferred over an I2C/SPI digital sensor.
When designing with the MPX4200A, place a 47 nF decoupling capacitor close to VCC and provide a stable, low-noise 5.1 V supply; ripple on VCC couples directly into the output because the signal is ratiometric. Shield the analog output trace from switching noise and use the device only in media compatible with silicon gel and plastic housing.

Aplicaciones típicas
MPX4200A es adecuado para 6 aplicacións: Turbo-Boost Engine Control, Engine Manifold Absolute Pressure Sensing, Barometric Pressure Correction, Industrial Pneumatic Pressure Monitoring, Altitude-Compensated Small-Engine ECUs, General Calibrated Absolute Pressure Transducer.
Turbo-Boost Engine Control
The MPX4200A's 20 kPa to 200 kPa absolute range maps directly onto naturally aspirated and moderately boosted gasoline manifolds, while its 0.3 V to 4.9 V ratiometric output feeds the ECU's ADC with no external amplification. At VCC = 5.1 V the sensor puts out roughly 4.65 V at 1 bar of boost, giving an ECU 80 % of full-scale dynamic range to resolve boost increments without saturating. The on-chip temperature compensation (1.5 % F.S. over 0-85 °C) lets the ECU skip in-field MAP calibration and reduces warranty exposure to drift. Plumbed into the intake manifold with a short rigid hose to avoid pulsation averaging, it is the de-facto MAP sensor for small-engine ECUs.
Recomendado
Engine Manifold Absolute Pressure Sensing
Manifold absolute pressure sensing is the textbook use-case for the MPX4200A: an ECU samples Vout every 10-20 ms, runs it through the datasheet transfer function Vout = VCC x (0.01058 x P - 0.1528), and feeds the resulting kPa value into a speed-density fuel map. The 6-SIP axial-port package lets the sensor mount directly on a manifold boss with a single O-ring seal, eliminating hose-induced measurement delay and failure modes. Its -40 °C to +125 °C operating envelope covers under-hood cold-start and sustained highway thermal load. Compared to discrete strain-gauge + op-amp solutions, the integrated ASIC reduces PCB area to a single 47 nF bypass cap and the analog input of an ADC.
Recomendado
Barometric Pressure Correction
Although optimized for manifold absolute pressure, the MPX4200A is frequently re-purposed as a sealed barometric reference on the ECU housing, where its 4.9 V full-scale output and 1.5 % error band over 0-85 °C provide more than enough altitude-correction accuracy for production engine management. Sampling at lower update rates (1 Hz or slower) keeps self-heating from the 10 mA supply current below 0.5 °C, preserving calibration. Compared to dedicated barometric sensors with digital outputs, the analog MPX4200A lets older analog ECUs add a barometric channel with one ADC pin and no firmware rework. For higher altitude resolution consider the MPX4115A, which spans 15-115 kPa.
Recomendado
Industrial Pneumatic Pressure Monitoring
Outside the automotive ECU, the MPX4200A is routinely used to monitor compressed-air manifold pressure on industrial pneumatic systems up to 2 bar absolute. The on-chip signal conditioning handles the long cable runs typical of factory-floor installations without picking up noise or losing calibration. Because the output is ratiometric to VCC, local regulation noise and IR drop on shared power buses cancel out of the measurement, giving more stable readings than offset-output transducers. The wide temperature envelope supports unconditioned cabinet installations from -40 °C cold storage to +85 °C boiler rooms with no extra thermal conditioning.
Recomendado
Altitude-Compensated Small-Engine ECUs
Motorcycle, ATV, marine outboard, and small-engine ECUs commonly pair the MPX4200A with a barometric pressure correction table to maintain fuel enrichment as the operator rides between sea level and high altitude. The 20-200 kPa absolute range cleanly covers altitudes up to about 5,000 m when paired with a sealed barometric sensor on the ECU case. An on-board ratiometric analog output simplifies the small-engine MCU, which often lacks I2C/SPI peripherals and would otherwise need an external ADC. Compared to an integrated digital pressure sensor, the MPX4200A trades firmware complexity for a single op-amp-less analog input.
Recomendado
General Calibrated Absolute Pressure Transducer
Wherever a 0-200 kPa absolute pressure reading is needed without designing a full signal-conditioning chain, the MPX4200A drops in as a calibrated analog front-end. The NXP transfer function Vout = VCC x (0.01058 x P - 0.1528) lets a microcontroller convert ADC counts directly to kPa without field calibration, supported by a 1.5 % F.S. accuracy spec over the production-relevant temperature window. Typical uses include HVAC refrigerant monitoring, gas-meter pressure safety cutoffs, and laboratory instrument pressure readouts where repeatability matters more than absolute accuracy. For higher resolution or digital output, swap to a digital barometer; for higher pressures, swap to the MPX4400A up to 400 kPa.

Notas de diseño
Place a 47 nF (or larger, up to 100 nF) ceramic decoupling capacitor as physically close as possible to the VCC pin (pin 1) and the GND pin (pin 2) of the MPX4200A. The sensor draws roughly 10 mA, and because the output is ratiometric to VCC any series inductance or IR drop in the supply line couples directly into the analog output. Use a low-impedance 5.1 V LDO or a post-regulator filter rather than the unregulated ECU battery rail, especially under cranking transients when battery voltage can sag to 6 V and the LDO maintains a stable VCC.
Route the Vout trace (pin 3) as a short, guarded analog line away from switching nodes, ignition coils, injector drivers, and parallel high-current traces; typical minimum separation is 3 mm or a ground guard trace stitched with vias to the ground plane. Use a small RC low-pass (10 kΩ + 1 nF, fc ~ 16 kHz) on Vout only if the rest of the ECU runs above ~50 kHz of switching noise; otherwise rely on the sensor's intrinsic bandwidth and a clean PCB layout. The three NC pins (4, 5, 6) must be soldered for mechanical retention even though they are not electrically connected internally - skipping them is a common field-failure root cause.
Do not pressurize the port above 400 kPa (roughly 2x F.S.) or expose it to liquid water or fuel - the silicone gel can rupture and contaminate the ASIC, permanently biasing the output. Do not connect Vout directly to a 3.3 V ADC: at VCC = 5.1 V the output swings to 4.9 V and overdrives the ADC; either run the sensor from a lower VCC (sacrificing the calibration transfer), use a resistive divider, or pick a digital pressure sensor. Finally, verify the O-ring is correctly seated against the manifold boss; an unsealed port on a 1-bar boost engine will leak under load and produce under-reading MAP values that an ECU interprets as knock retard, killing fuel economy.
