Pinouts
The UDA1334A is an I2S amplifier - it does not use analog inputs, it only has digital audio input support! Don't confuse
I2S with I2C, I2S is a sound protocol whereas I2C is for small amounts of data.
Power Pins
The UDA1334A requires 3.3V power but can take 3-5V
level logic on nearly all pins.
You can provide 3-5V power on the VIN pin and GND
and the built in regulator will generate a nice clean 3.3V
supplier on 3VOut.
Use the quietest power supply for Vin, we do filter the
power supply, but the quieter the better!
