I.C. Identification

Hello all,

The I.C. is an 8 pin DIP and has the number 'A2211', a date code and
what looks like a backwards 'R' followed by a 'U'. While the repair work
didn't involve the I.C. this time, I'd like to find the datasheet in
case I have to deal with it in the future.

The manufacturer of the amplifier will not supply a schematic until the
unit is out of production (very common for manufacturers of class D
amplifiers - some never provide schematics). It looks like it's being
used as a buffer or possibly an inverter (all signals look identical).


Any help would be greatly appreciated.
