There is an open ended warning in the datasheet for the INA333-HT:
"It is not recommended to use a gain < 100 for high temperature (210°C) applications. For gains > 100 in such applications, a compensation circuit is needed at pins 1 and 8. The circuit is needed at each pin and consists of a resistor in series with a capacitor referenced to ground. Recommended values for the resistor and capacitor are 3.5 kΩ and 10 nF respectively."
Two big questions come up:
1) What happens to the IN amp performance at 150°C or 175°C? Can I use the part with gain < 100 at those temperatures?
2) What will break if I use it with gain = 1 at 210°C?
Thank you in advance for your thoughts.
