I want to use a TPA6111A2 with a split supply.
As you may know, it's pin-for-pin compatible with the old Nat'l LM4881.
It's designed to be used with a single 5V supply - along with output capacitors.
Why I like this old chip is that it can easily drive 16 ohm loads - even small 8 ohm speakers!
But I'm looking for someone who has successfully accomplished this (using it with a split supply).
Here is the circuit as I see it so far - but has ANYONE made this work (with a split +/- power supply?)
What do you do about pin 3 "Shutdown" or pin 1 "Bypass"?
