Hello,
Our customer input 6Vpp 60~150kHz Sin wave,
When they input high code to the DAC, there is no problem.
However, if they input the value of 50 or less in decimal, the output was not decreased any further.
Could you please let me know the probable cause of this issue?
For low output code, they change the Ref input voltage from 6Vpp to 0.3Vpp.
They use AD8512B to the I/V amplifier and Cfb is 68pF.
I can send the schematics if you contact the following e-mail address.

Best Regards,
Ryuji
