[ TAS5421 ] I2C Communication Wait Time after Power-Up

Hi,

The datasheet suggests approx 1ms wait time to enable I2C communication after releasing of STANDBY_ pin.

Do you have any requirement on I2C wait time after power up?

Thank you for your support in advance.

Regards,

Ken

Hello Ken,

There is no wait time requirement for I2C after power up. The sequence should be: power up, de-assert stand-by, wait 1mS, I2C read/write.

Hope this helps.

Thanks,

Tuan
