Looking at the circuit diagram it follows the classic op-amp with a long-tailed pair of NPN transistors driving a PNP gain stage and finally a complimentary emitter follower as an output buffer.

That’s the infinite gain. Any positive or negative output ... Rather than dig through a lot of math, you can deal with nearly all op amp circuits if you remember two simple rules: The inputs ...

Despite the monolithic op amp being older than SPICE simulators, comprehensive op-amp SPICE modeling left a lot to be desired ...

To look at CMRR above 1 kHz, you might use R 100c ~ 2k to give good results up to 10 kHz. In other words, you have to ...

You need a TVS diode because many voltage regulators do not have the ability to sink current, nor can they respond fast ...
