I am selecting an amplifier as the Pre-Amp of a VGA and I comes to ADA4004
The datasheet provides detail performance data but not the Input Impedance (Res and Cap)
Where can I access those information?
Thanks for your warm response and the revision on the spec.
As I am trying to involve this in an audio system as the input stage, I would like to configure it as a G=-1 Inverting Amplifier with frequency compensation circuit record as follow:
Vin 1 0 (Signal Source)
XAD4004 2 0 99 (- + Output)
Rin 1 2
Rfb 2 99
Ccompfb 2 99
CcompGnd 2 00
Rin would be range from 1~5K
and capacitance aimed to set a -3db pole @ 500K to provide better stability.
I can estimate the impedance of the source from 1~50 Ohm as they should be driven over long wire and a output buffer should be there.
Retrieving data ...
