Hi,
Our customer has a question about EN PIN of LM3881.
The calculation formula is shown as follows.
T=1.22V x C / 7uA (D/S P11)
Is it necessary to consider variations in the reference voltage of the comparator?
Specifications are 1.0 Vmin to 1.5 Vmax over temperature. I think that it is difficult to fix to an appropriate value because it is wide.
On the other hand, it is not so wide(1.21V ~ 1.23V) in Figure 3. "Enable Threshold vs Temperature".
Please give me advice.
Thank you.
Hiroshi.
