*Non-compensated pressure sensors, excited constant current instead voltage, exhibit temperature compensation Span. Application Note briefly discusses current excitation. Constant current excitation additional benefit temperature measurement. When driven constant current source, silicon pressure sensor's terminal voltage will rise with increased temperature. rise voltage only compensates Span, also indication temperature.
