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.
