Please let me know about two point below of TPA0253 and TS5A23159.
--------------------------------
【Background】
・TPA0253 and TS5A23159 Circuit is attached below.
・Customer want to change Gain-setting for Speaker output(BTL) and Headphone output(SE) separately.
【Question】
①Is this way of Gain-setting correct?
Is there concern point(noise, etc), please let me know.
②When used case of Mono Speaker, "SPK_SW" turn L-level.
But, I think that SPK_SW line will overlap voise sound signal.
⇒When case of large sound, is TS5A23159 no problem or not?
