Hi Kiran,

I would recommend you to tale a look to the TAS5611A, this device has analog inputs and offers the same power performance of the TAS5622A.

If you want to use TAS5622A, you may need to add an ADC to convert the analog input to digital audio, then a PWM modulator that will convert digital audio into PWM output for the amplifier.
