PLLXO & input impedance

[chris4916]

Hi,
Who ever measured (or knows) AMP9 input impedance ?
I'm asking this because I plan to try PLLXO with AMP9 and I'm just wondering how to take this input impedance while designing filter.

Cheers,

Christian

50k ohms per the datasheet. range is 43-57k ohms.

Hi Chris,

I have made several PLLXO configurations that work very well with my AMP9, what speaker system do you intend to drive with it?

------X-max. can be several meters on any driver, too bad it can be done only once...------
