PCM2704C: Suspend current capability

Hi Joao,

Just to clarify, you are asking about pin #27 VCCL, and pin #7 VDD? We can check to see if we have this information over temperature. Please expect a delayed response due to the holiday weekend in the US. 

Best,

Katlynne Jones

Hi Katlynne

I am asking about SSPND and not VCCL.

I understand holiday weekend.

thanks

I also would like to know about the HID inputs.

The datasheet seems to not have much about it.

In particulary, I would like to know the input impedance and if there is any low pass filter to avoid detecting spurious changes on HID inputs.

Many thanks

Joao 

Hi Katlynne

I have confirmed from datasheet the following: 

“but any other active component must not use VCCP, VCCL, VCCR, or VDD as a power source.”

conclusion: I cannot use VDD so I do not need VDD output current!

I am sorry for not seing this sooner.

We will take a look at this tomorrow after the US holiday. 

Thanks,

Paul

Hi Joao,

My apologies, I was originally looking at the pinout for the PCM2706C/7C where pin #27 was VCCL. For SSPND, the absolute maximum input current for any pin (other than the supplies) is ±10mA. That value is given over temperature. 

Paul should be able to give you more information on the HID inputs. I did some initial searching, but he is the expert in these devices. He will be back in the office tomorrow. Sorry for the delay.

Best,

Katlynne Jones

Hi Katlynne

Thank you.

I guess that if you say ± then I can conclude that the max output current is = max input current = 10mA?
