I need to replace a M5229P graphic equalizer chip. Basically it's
just 8 opamps with internal resistors configured so that 2 pins of
each amp connect to the outside world to make inductance gyrators for
a filter bank. Here is a diagram:

The chip is out of production and there are no obvious direct
replacements. There is a similar chip, the BA3812L, which has
transistor arrangements to do the same thing. You can see it here:

I know I could replace this with 4 quad op-amps and 30 resistors and
get the same functionality, but if anyone knows of another chip that
is even remotely similar in function, please let me know.
