Other Parts Discussed in Thread: LM339
Dear team
We used two batches of LM311DR, but the working frequency of one batch was unstable.
The normal working frequency was 192KHZ, but it sometimes ran to 96KHZ. Attach test pictures and videos.
We checked their top marks, and polarity points and lines appeared on the equipment with unstable output frequency.
How should we debug the product? Please help provide professional advice, thank you
