請教OPA627, OPA637 起震問題

1. Check the original op-amp circuit about the GAIN.

2. If the Gain is < 5, cannot use OPA637.

Just like MHZ66, if not observe the CRO, you don't know the output waveform is clip (for some model, it is a human error)

If you understanding the circuit operation clearly, you may not need to mod all compoents will have great result.

See the datasheet for reference.

Modification is not too difficult.
