你部機看D料.作者: kk_ho 時間: 2007-3-27 10:30
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.

thank you KK sir.
