Hi Scott,

        I've got an old national data book so I'm not sure the PDF is the same.

        Just a guess from what you've said, and not knowing how you have it
hooked up, is it possible you don't have a negative voltage at pin 3. I
doubt this chip will work with a single power supply.

        Are you using an OPAmp or resistor to convert the current output
into a voltage?

        Or is it possible the chip is "pins up", do you have another to try?

Regards,
Heinz
