*Non-compensated pressure sensors, excited by constant current instead of

voltage, exhibit temperature compensation of Span. Application Note #1

briefly discusses current excitation.

Constant current excitation has an additional benefit of temperature mea-

surement. When driven by a constant current source, a silicon pressure

sensor’s terminal voltage will rise with increased temperature. The rise in

voltage not only compensates the Span, but is also an indication of die

temperature.
