Hi Team,

Is it possible to switch amplifier input(IN1 and IN2) dynamically?
He wants to switch within 20ms.
I would like to know it for both hardware mode and software mode.

Best Regards,
Yaita

    Hi Yaita-san,

    Yes, LM48560 is able to swap IN1 and IN2 on-the-fly.
    It takes around 13.5 mS to change between channels.
    For software mode, these 13.5 mS are counted after the I2C writing sequence is completed.
    For hardware mode, these 13.5 mS are counted after the SDA/SEL pin is changed from VDD to GND or GND to VDD.
    I hope this helps.
