Our customer encounter below issue:
After the signal output by the DAC passes through the THS3001, the total harmonic distortion of the 1MHz signal is -68dB. From the data sheet, the THD is less than -96dB.
So is there any problem with the op-amp? Thank you.
The op-amp circuit is as follows: The front stage of the op-amp is the DAC current output; the rear stage is the filter.
