PCM1754-Q1: VOUTL & VOUTR Pin Current drive

Hi Archie,

We need more details from you to answer your question. What kind of details are you looking for? 

Hello Jeff,

Thanks for responding.

Customer is asking the output current of the two pins VOUTL & VOUTR. D/S states these two unbalanced outputs, each capable of driving 4 VPP typical into a 5-kΩ ac-coupled load.

Thank you.

Regards,
Archie A.

I shall respond tomorrow. I apologize for the delay

Hi Archie,

The datasheet lists a maximum voltage of 4Vpp = 1.414 Vrms and a minimum load of 5 Ohms. This means the maximum current output is 1.414/5 = 0.283 mA. The load can be higher and will reduce the current draw, but a smaller load will draw more than the max current. 

Assume that the Load Resistance is ac coupled from the amplifier output.

The Peak allowed current into this load is 0.283*1.4114 or 0.4ma.
