Drive AD9681 single-ended

Hiroyuki.D on Nov 5, 2020

I'm a DFAE in Japan. Our customer considers driving the AD9681 inputs single-ended. Is it possible? If it is possible, could you please tell me the recommended driver circuit?

Regards,

Hiroyuki

Hi Hiroyuki-san,

Thank you for promoting the AD9681. Unfortunately the AD9681 cannot be driven single-ended.

I'm sorry about that.

Hello Doug

Thank you very much for your quick response. Is there any IC with specifications similar to the AD9681 that allows single-ended input?

Regards,

Hiroyuki

Hi Hiroyuki-san,

From information in the datasheet it looks like the LTM9012 can be driven single-ended. Its performance is not as good as AD9681.

Thank you.
