Our customer asked as folowing question.
As for your ADA4851-1,
What is your output leakage current when /PDN is enabled?
In fact, he has put the transistor 2SC6075 at ADA4851-1 output, and has driven the laser diode.
But when he change /PDN=enable, then 2SD6075 worked and the laser diode came on.
He think the reason why is leakage current.
So I need your comment soon.
