Media Resistant and

High Temperature Accuracy

Integrated Silicon Pressure Sensor

for Measuring Absolute Pressure,

On-Chip Signal Conditioned,

Temperature Compensated

and Calibrated

Motorola’s MPXAZ6115A 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 MPXAZ6115A 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.
