Application Note #1 briefly discusses current excitation. Constant Current Excitation Schematic Constant current excitation has an additional benefit of temperature measurement. 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. 10 Honeywell 1 MICRO SWITCH Sensing and Control 1 1-800-537-6945 USA 1 F1-815-235-6847 International 1 1-800-737-3360 Canada
