Hi Team,

My customer plan to use TPA6132A2 for their headphone amplifier and they plan to have three port output with this source. Do we have suggestion for the splitter? 1:2 or 1:3 are fine.

Regards,

Roy

Hi Roy,

Can you share a diagram of the amplifier and load connection?
Do you need to drive 2 different speakers with the same amplifier output?

Hi Ivan,

Yes. Please see below. Please ignore the TS5A23157, it's wrong solution.

Regards,

Roy

Hi Roy,

Perhaps you can just use 3 separate headphone amplifiers and control the EN pin.
Otherwise, the switch device would have to support positive and negative voltage range for the GND centered output from TPA6132A2. Or use a buffer that you can disable, but the buffer must have similar characteristics.

Hi Ivan,

Do you mean that just use OPA(voltage follower) to achieve our application?

Roy,

My first suggestion is use 3 TPA6132A2, each driving a different load.
