LM3881: MIN MAX value for TADJ

Kei Kuwahara

Part Number: LM3881

Hello team,

The datasheet states that

"Considering the TADJ voltage threshold levels and the charge/discharge current magnitude, it can be shown that the timing capacitor-clock period relationship is typically 120 µs/nF."

Is there any MIN / MAX value for this parameter?
If there is no MIN / MAX data, what is the reasonable estimation for the variation?

Best Regards,

Hello yihe-san,

Thank you for your reply, but I am not looking for MIN/MAX capacitor value, which can be connected to TADJ pin.

I am looking for variation data for timing capacitor-clock period relationship, which is stated typically 120uF/nF.
Is there any ATE data for MIN/MAX value? or if there is no ATE data, then should I estimate it as +/-20% from the TYP value?
