Hello,

I would like to know what is the maximum amount of current that can be input to the DDC112UK analog input?

I would like to input a current close to 2mA, is it possible?

since according to the datasheet the maximum input charge ialong with

Enternal capacitor is 10000pC which gives a max input current range upto 2uA only.

Saloni,

I'm moving this post to the Medical Forum, where the DDC products are supported. I'm sure you'll find an answer here.

Saloni,

Unfortunately as you already mentioned, the DDC112 cannot handle the higher current that you would need. What is your application, maybe we can help you find a device that would work for this.

Regards,

Adam,

Thank you for your reply. Actually I am using a PSD (Position sensitive device), it is a sensor which outputs current and I need to digitize it's output.
