w*Non-compensated pressure sensors, excited by constant current instead of
wvoltage, exhibit temperature compensation of Span. Application Note #1
briefly discusses current excitation.
w omConstant current excitation has an additional benefit of temperature mea-
.csurement. When driven by a constant current source, a silicon pressure
Usensor’s terminal voltage will rise with increased temperature. The rise in
t4voltage not only compensates the Span, but is also an indication of die
