## SPECIFICATIONS 

- **PC Board Mountable Pressure Sensor** 

- **0-100 mV Output** 

- **Current Excitation** 

- **Gage and Differential** 

- **Temperature Compensated** 

The 23 and 33 are temperature compensated, piezoresistive silicon pressure sensors packaged in a TO-8 configuration. It provides excellent performance and long-term stability. 

Gage and absolute pressure ranges from 0-2 to 0-250 psi are available. Integral temperature compensation is provided over a range of 0-50°C using laser-trimmed resistors. An additional laser-trimmed resistor is included to normalize pressure sensitivity variations by programming the gain of an external differential amplifier. This provides sensitivity interchangeability of ±1%. 

Please refer to the 23 and 33 1 psi datasheets for low pressure applications.

## **Notes** 

1. Ratiometric to supply current. 

2. Best fit straight line. 

3. Maximum temperature error between 0°C and 50°C with respect to 25°C. For 2 psi devices, Temperature Error – Zero is ±1.25%. 

4. For a zero-to-full scale pressure step change. 

5. Minimum resistance between case and pins. 

6. Long term stability over a one year period with constant current and temperature. 

7. For topside applications, 2X maximum for 250 psi device, 20 psi maximum for 2 and 5 psi devices. For backside applications, 3X not to exceed 100 psi on all ranges.
