OTAs, How do they work?!

[Aleph Null]

I'm trying to understand the LM17300, but haven't been able to find much information beyond the data sheet. Explainer articles or videos all insist on using a split power rail and don't do much in the way of practical examples. Does anyone have a source that shows how to use an OTA as an amplifier (as opposed to a resistor, or in a filter)? I'm especially interested in examples of using an OTA without a split power rail.

Thanks, all. I know someone here must have some experience.

There are some application notes for the ca3080 here

A ross-style compressor is an application like you want (single power supply and amplifier). E.g. https://www.madbeanpedals.com/projects/_folders/Compressor/pdf/Kompromat.pdf.

Spaceman Effects Aphelion is also a very interesting ota-based pedal (diy board and schematic here https://www.deadendfx.com/product/anticarus)

Thanks. I knew the Ross had an OTA in it, but I thought it was being used as a voltage-controlled resistor—I should have looked close at the schematic. The Aphelion actually appears to be doing what I want to do; saturate the OTA. I'll definitely be looking into that.
