opAMP input on Giga R1?

Official Hardware Mega GIGA R1 WiFi

Looking at the official pinout PDF file for the Giga R1 I see that the A0,A1,A2 pins are marked also as "OPAMP_OUT, OPAMP_IN-, OPAMP_IN+". This leads me to believe there is an actual opamp built into the Giga board connected to these pins? Is this true?!?!

If it is, where are the electrical specs on this OPAMP. And how would I access it?

The STM32H7 has an internal op amp and comparator, with connections that are exposed on the GIGA R1.

The details are in the processor data sheet.

I made a library that allows you to use it in set gain mode, though it’s mostly focused on other things - GitHub - Bexin3/STMSpeeduino: Speed up functions on your STM32H747 based Arduino

Thanks. I'm mainly going to use it for an audio input pre-amp with a 20Khz low-pass filter
