Motorola Sensor Device Data

Integrated Silicon Pressure Sensor

for Manifold Absolute Pressure,

Altimeter or Barometer Applications

On-Chip Signal Conditioned,

Temperature Compensated

and Calibrated

Motorola’s MPX4115A/MPXA4115A 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

Motorola pressure sensor a logical and economical choice for the system designer.

The MPX4115A/MPXA4115A 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.

Figure 1 shows a block diagram of the internal circuitry integrated on a pressure

sensor chip.
