We are planning on using the LM26 in order to drive a circuit as a PCB heater when the temperature drops below -25C.
However, The LM26CIM5-DPB VTEMP Output (TEMP_SENSE) is steady at .96V which would correlate to ~110 degC but this is in a normal room environment ~25degC.
PCB Temp is ~30degC which should correlate to a VTEMP output voltage of ~1.8V.
Is there something in my setup that would cause the output voltage to be stuck at an improper voltage?
Any thoughts or suggestions are helpful.
