23 and 33 1psi 23 33 • PC Board Mountable Pressure Sensor • 0-100 mV Output • Current Excitation • Gage and Differential • Temperature Compensated DESCRIPTION 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. 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 standard datasheets for information on products with operating pressures greater than 1 psi.
