The AN6550 is a dual operational with a phase compensation and low voltage operation mode ....the question is ...are u constricted by the low voltage usage mode ? or not .I found those ....surfing and as i see there are some goodies bonus ....slew rate and so on ....didn't checked the equivalence but this worths to be seen.

Take care though tere are many parameters that can be modified...as i understand that u intent to use it in a microphone stage.
