Constant Current Excitation Schematic
*Non-compensated force sensors, excit-
ed by constant current instead of voltage,
exhibit temperature compensation of
Span. Application Note #1 briefly dis-
cusses current excitation.
Constant current excitation has an addi-
tional benefit of temperature measure-
ment. When driven by a constant current
source, a silicon pressure sensor’s termi-
nal voltage will rise with increased tem-
perature. The rise in voltage not only com-
pensates the Span, but is also an indica-
tion of die temperature.
