Hello everyone,


I am developing a USB audio interface and for the headphones output I have selected the SSM6322 .

I have some doubts, the first one is what is the Input mA that the amplifier needs.

The second is that for 70 Ohm headphones what I should choose,

Figure 46. Circuit with Current Output DAC or Figure 47. Circuit with Voltage Output DAC of the datasheet.

Thank you so much.


Best regards
