In what cases is the automatic zeroing of the op-amp (Operational Amplifiers) used?

Question

Circuit design

I can't find information on this issue.

Answer 1

For example, if the following requirements coincide:
1. With a given DC error at the output and the required gain, the required input offset must be less than that of existing / available op-amps without adjustment. Those. without adjustment / compensation we can not.
2. Requirements for temperature and/or time stability and/or CMRR do not allow the use of type adjustment through balancing pins. A balancing resistor can degrade any of these parameters.
3. The frequency range of the signal allows you to use a more (?) "noisy" op-amp with auto-tuning.
