for a project I need to be able to amplify some signals in order to drive an ADC. I experience some problems/strange behaviour but perhaps I'm making some wrong decisions.
My signals are three times amplitude modulated signals of max…
We use AD8336 because the input signal is positive and negative 5V, if AD8331 is not used, the input signal to be processed, in order to enter the AD8331？
AD8331 Theta Jc : 33.61 C/W.Regards,Goz
We want to use the AD8331 in our new project as AGC Amplifier at ADC input stage.
In this project, the input frequency range is 20KHz to 500KHz.
Datasheet contains the plots showing only from 100KHz.
Ad8331 can support the 20KHz input?.
This is Dominic Ying.
I'm trying to use the spice model downloaded from ADI website to simulate the VCM function of AD8331. But when I applied the suggested circuit to set the common mode voltage to 2.0 V, but the common mode voltage of AD8331 output…
I need to cascade two amplifier AD8331. Second amplifier should be connected without LNA. Can i connect it this way?
I already contacted the experts for AD8331 and will get back to you as soon as I have the information.
Please see AD8331/2/4. It is a VGA with an integrated LNA and programmable input impedance.
