High Temperature Accuracy
Integrated Silicon Pressure Sensor
for Measuring Absolute Pressure,
On-Chip Signal Conditioned,
Temperature Compensated
and Calibrated
Motorola鈥檚 MPXH6250A series sensor integrates on鈥揷hip, 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鈥揷hip integration make the Motorola pressure
sensor a logical and economical choice for the system designer.
The MPXH6250A series piezoresistive transducer is a state鈥搊f鈥搕he鈥揳rt, 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.
