TPA2012D2： GND connection with OUTR-, OUTL-

Part Number: TPA2012D2

Connect to 2.5mm jack with CTIA.

Is it okay if the OUTER- and OUTL- signals have the same GND connection?

Or does it have to be separated?

CTIAで2.5mmジャックに接続します。

OUTER-信号とOUTL-信号のGND接続は共通でも問題ありませんか？　・・・Common GND connection

または、分離しないといけませんか？　・・・Separate GND connection

    Hi,

    Welcome to E2E and thank you for your interest in our products!

    Please use the common GND connection scheme, both speakers output must share the same ground as shown in your second picture.

    Please let me know if you need additional support from our side.

    Best regards,
