Hello,
We are currently out of office right now due to holidays, and we sincerely apologize for the inconvenience. We'll get back to you soon.
Best regards,
Paul
It's okay. You'll get back to me at work. Have a good holiday
Hello Mark,
Can you provide the specific input details that you used in your circuit (amplitude, frequency etc.)
Thanks,
Kenneth
Thanks to your reply. The input signal Vpp=100mV,25khz,used function generator TFG6960A.Through an instrument amplifier amplification to VPP=16V, and then to the AD8676.
Hello Mark,
Sorry for the delay in response. Can you give the actual ampifier part that you used to amplify the signal before the AD8676?
I will try to simulate your circuit in LT Spice first to check initial performance.
Best Regards,
Kenneth
