The 1220 1psi is a temperature compensated, piezoresistive silicon pressure sensor with a 0-1 PSI measurement range.  When using the 1220 with a fixed voltage reference and current set resistor as shown in the application schematic, a span of 50mV and 1% interchangeability can be achieved. Integral temperature compensation is provided over a range of 0-50°C using laser-trimmed resistors. Please refer to the 1220 standard datasheet for information on products with operating pressures greater than 1psi. For current excitation, please refer to the Model 1210. 


  • Dual-in-Line Package 
  • 1.0% Interchangeable Span (provided by current set resistor) 
  • ±0.3% Non Linearity 
  • Solid State Reliability
