Part Number:TPA3221
Hi,
A customer wants to drive a 100-ohm loudspeaker by TPA3221, in either way shown below.
(A) impedance conversion with an output transformer for audio amplifier
(B) impedance conversion with a switching transformer, in previous stage of LC filter
He wants to know about technical concern points of these methods.
If you notice some problem, could you tell us about it?
Best regards,
Akio Ito
