Does TS5A22362 support audio amplifier output signal, if audio source is 3.6W RMS output？

Hola Adam,

I have one more question：

We will use TS5A22362 to headphone and speaker output.

Does TS5A22362 support audio amplifier output signal, if audio source is 3.6W RMS output？

Audio amplifier chip is TFA989x. TFA989x datasheet web address is as below：

    Hi Jacky,

    Here is the response from Ravi:

    Meanwhile, here are my notes.

    The RMS power handling capability of the switch is a function of Vrms (External Signal swing) & Irms (current allowed through switch)
    Section 6.1 in the data sheet specifies the abs-max continuous current (Irms spec)
    The product of Vrms * Irms will give you the power handling capability.

    Please note for a symmetric audio signal swing, you will need to use Vcc=2.75V (as described in section 8.3.1 of the datasheet)
