LM4950: Differential input to BTL output on the LM4950

Gordon Rankin

Part Number: LM4950

I am designing a Bluetooth mono speaker amplifier and my BT module has differential analog outputs.

Is it possible to modify the BTL so the B channel carries the negative leg of the differential side of the input and it's feedback path comes off the negative terminal of the speaker?

Thanks,

Gordon

Hi Gordon,

Can you share a diagram of the connection you want to make?
I don't get the difference between what you mention and what is shown in the data sheet.
