TLV320DAC3101: Application issues.

Hello,

On our EVMs we often use xmos or TAS1020 IC with our dacs and amplifiers , so  the above  is feasible.  The SPK output pins need a load of 8 Ohm Min and the HP pins a min load of 16 Ohm. You can always refer to users guide in the product page for the schematic reference.

I  would add 22 to 100 Ohm series resistors on I2S signals and ground any unused analog input pin via a cap.

if  your interested you can also refer to   SLVA689–February 2015    I2C Bus Pullup Resistor Calculation
