MPXxx6115A Series(MPXA6115A, MPXAZ6115A, MPXH6115A, MPXHZ6115A)

General description

The MPXxx6115A series sensor integrates on-chip, bipolar op amp circuitry and thin film resistor networks to provide a high output signal and temperature compensation. The small form factor and high reliability of on-chip integration make the pressure sensor a logical and economical choice for the system designer.
The MPXxx6115A series piezoresistive transducer is a state-of-the-art, monolithic, signal conditioned, silicon pressure sensor. This sensor combines advanced micromachining techniques, thin film metallization, and bipolar semiconductor processing to provide an accurate, high level analog output signal that is proportional to applied pressure.

Feature
  • Resistant to high humidity and common automotive media
  • Improved accuracy at high temperature
  • Available in small and super small outline packages
  • 1.5% maximum error over 0 °C to 85 °C
  • Ideally suited for microprocessor or microcontroller-based systems
  • Temperature compensated from -40 °C to +125 °C
  • Durable Thermoplastic (PPS) Surface Mount Package
Application
  • Industrial controls
  • Engine control/manifold absolute pressure (MAP)
  • Weather station and weather reporting device barometers

Feature :
Command to start AD conversion.

Process :
1. AD conversion start.

Command API function :
etSTS oMPXH6115A_START( void )

Return value :
eSTS_FIN
eSTS_ERR_HAL_ADC
eSTS_ERR_COMMAND_CODE

NOTE :
Arduino, Mbeb, ModusToolbox not supported.

eCMD_READ

Feature :
Command that reads the AD conversion value, converts the AD conversion value to a characteristic Pressure, and stores the Pressure in rlt.

Process :
1. Read AD conversion value.
2. Convert AD conversion value to Pressure.
Voltage value = (AD conversion value × VDD) / (2AD bit )
Pressure = ((voltage value – voltage offset value) / gain) + Pressure offset value (Min, Max Limit)
3. Store Pressure to rlt.

Command API function :
etSTS oMPXH6115A_READ( float32* rlt )

Return value :
eSTS_FIN
eSTS_ERR_MIN
eSTS_ERR_MAX
eSTS_ERR_HAL_ADC
eSTS_ERR_COMMAND_CODE
eSTS_ERR_OTHERS_RUN
eSTS_ERR_ADC_OBJECT

NOTE :
Please execute this API function after starting AD conversion.
Arduino, Mbeb, ModusToolbox not supported.

eCMD_START_READ

Feature :
Command that starts AD conversion, waits for AD conversion to finish, reads out the AD conversion value, converts the AD conversion value to a characteristic Pressure, and stores the Pressure in rlt.

Process :
1. Read AD conversion value.
2. Wait until AD conversion is completed.
3. Read AD conversion value.
4. Convert AD conversion value to Pressure.
Voltage value = (AD conversion value × VDD) / (2AD bit )
Pressure = ((voltage value – voltage offset value) / gain) + Pressure offset value (Min, Max Limit)
5. Store Pressure to rlt.

Command API function :
etSTS oMPXH6115A_START_READ( float32* rlt )

Return value :
eSTS_FIN
eSTS_ERR_MIN
eSTS_ERR_MAX
eSTS_ERR_HAL_ADC
eSTS_ERR_COMMAND_CODE
eSTS_ERR_OTHERS_RUN
eSTS_ERR_ADC_OBJECT
