Motorola’s MPXAZ4115A 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 MPXAZ4115A 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.
