Subject: Opamp temperature compensation (variometer)

Hi,
I need for a variometer (vertical speed indicator) a
solution to compensate temperature drift of the opamps.
I use quad MCP604 (Microchip), these have 2,5uV/Celsius. With
a 2000 gain will give 2,5 mV/Celsius, totaly inacceptable.
I have a remaining opamp in the capsule, I must do the compensation
with it and as minimum components possible (no thermistor, etc.).
I must use these opamps, I can't buy anything else.
For Adrian Mills: How do you accomplished this task ?
Thanks,
Cosmin
