Other Parts Discussed in Thread: TAS5342LA, TPA3140D2, TPA3118D2

We are looking for the audio amplifier meeting following spec.

PWM input

2ch (BTL) : 10W/ch , 6ohm

1ch (PBTL) : 20W , 6ohm

Supply : 12V/3A

At first, we reviewed TAS5342LA but according to the datasheet its efficiency seems to be around 70% at 10W.
We want more efficient one.

Do you have any other recommendation?

Hello,

My recommendation would be the TPA3140D2 or TPA3118D2.

Best Regards,
Matt

Hi Matthew

Thank you for your reply.
They seem not to support PWM input.

But we refer them as recommended ICs which have good efficiency.

Best regards
