Some German page mentions HA-5002 from Intersil as a possible alternative. I can't evaluate how true this statement is. Slew rate and Bandwidth seem similar.

I made reference of Mr. Krzysztof Marcinek's design to build my MAX038 function generator. AD811 is used in the output stage. It's hot so I put a heat sink on it. The generator works fine for me so far.

You can find the updated schematic from the URL
http://www.kafka.elektroda.eu/podstrony/MAX038.php

Please note the diodes across the two LM337 for protection on the negative side for 5V and 15V supply are in wrong direction!

When I searched for 2000V/µs I came across this:

The suggested AD811 seems to be even better speced.

Meh whatever,
