What happens if I leave the null pins floating on an Analog Devices AD711?
Null pins is use to compensate the offset of the device and leaving it floating when it is not intended to use is advisable and basically, it should not show any effect on the performance of the device.
Why did you choose AD711? what is your application if you don't mind sharing it? You may want to consider ADA4000-1 which is our nearest alternative for AD711.
Thanks for the clarification. This question came from a customer of mine. The application is biologic spectral testing. Thanks for the heads up on the ADA4000-1, I will pass this info along to the customer.
Other op amp that is worth considering is ADA4610-1. It has higher speed, lower noise, lower bias current and lower current, RRO with better drift.
