Hi PYTsai,

Thank you for your post, I can help you.

OPA1678 may work, it depends on the application / requirements. What is the frequency and amplitude of the input signal? What is the expected output signal? What is the expected THD performance?

Hi Tamara

The input signal is audio signal 20 ~ 20KHz, and the amplitude is 2.8Vrms

The desired output signal is single ended audio signal, 4V rms, and the target THD is 0.0001%

The loading > 1K ohm

Would you suggest the suitable device ?

Do you need single-ended or differential output?

Hi Andy,

We need single-ended output.
