Silicon Pressure Sensors Ultra Low Pressure Sensing DC Series FEATURES • Ultra Low Pressure Sensing, down to mBar • ASIC Technology • Available in Gage and Differential Pressure Ranges • Available in Ratiometric and Regulated • Temperature Compensated over 0 °C to 50°C [32 °F to 122 °F] • Combined Linearity and Hysteresis error < % Span TYPICAL APPLICATIONS • Medical Instrumentation • HVAC • Environmental Controls • Portable Monitors GENERAL DESCRIPTION The DC Series pressure sensors combine SURSENSE precision high sensitivity silicon sensing capabilities with the latest in Application Specific Integrated Circuitry ASIC technology to produce one of the most precise, reliable pressure sensors in the market. The SURSENSE technology provides Dynamic Self Compensation which substantially reduces offset errors due to changes in temperature, stability to warm up, long term instability and position sensitivity. When operated with an unregulated Vdc to Vdc supply the DC sensors provides a ratiometric to Vdc output Vdc span .
