The heater control circuit in Figure 1is re-quired for operation per specifications.The sensing bridge supply circuit in Fig-ure 2 is also required for operation per specifications. These two circuits are not on board the package and must be sup-plied in the application. The differential amplifier in Figure 3 is a useful interface for the sensing bridge. It can be used to introduce the gain and to introduce volt-age offsets to the sensor output as refer-enced in Equation 1.Note: For applications sensing hydrogen or helium, see Application Note 3, page 131.Figure 1Heater Control CircuitFigure 2Sensing Bridge Supply CircuitFigure 3Differential Instrumentation Amplifier CircuitEquation 1:V o ⍧2R 2+R 1R 4V 2-V 1+V offset()()()R 1R 3where V offset ⍧V S()R 6R 6+R 51-800-537-6945 USA 1-815-235-6847 International 1-800-737-3360 Canada 691. Output Voltage is ratiometric to supply voltage.2. Temperature shifts when sensing differential pressure correlates to the density change of the gas over temperature.See Application Note 1.3.
