Other Parts Discussed in Thread: LM3881

Hello,

My customer uses the LM3881, has some questions.

Q1) How about the variation of the IEN(EN Pin Pullup Current) value due to the process variation?

Q2) Is there a correlation between VEN value and IEN value?

Off course, I explain my customer it is not guarantee this value.

Could you give me the answer the above questions?

Regards,

Hi,

At room temperature, and VEN = 0, IEN can typically vary aroun 6uA to 7.2uA.

Across the device's entire temperature range, you can typically expect another 0.5uA of variation.

I don't recall any data that tests IEN across VEN.
