Other Parts Discussed in Thread: TLV8801
Hi,
I use TLV8801 for ADC input buffer. I found OPA output will generate a sin wave, but if I remove the resistance between OPA and ADC, this sin wave is gone.
OPA input is voltage divider. Ru=1MOhm, Rd=1MOhm.
If I pass OPA, connect voltage divider to ADC directly. Then I can get correct voltage!
I don't know why this result, pls help give me right answer.
