Hi,

Need a low-power USB, Audio device class 2.0 to I2S bridge,

so looking at FX2LP FX2LP18 to do this in combo with some ARM cortex CPU.

What power consumption should I expect when running say a 44.1/16 bi-directional uac2 stream using hte FX2LP?

Thanks David

Hi David,

We have two USB 2.0  controllers, FX2LP and FX2LP18. FX2LP has a power dissipation of 300 mW and FX2LP18 has of around 220 mW. Both are the similar in functionality and can be used as an Audio class device. You can check the specific differences from this Application Note.

Best Regards,

Hi David,

Please specify if you are asking about the power consumption of only FX2LP or the complete system for your application?

Hi Sananya,

Preferably whole system if you happen to have an idea.

Note we can use any usb bridge-chip, not neccesarily FX2LP, so please propose the one with the lowest power consumption.

thanks
