I need a help in completing my Project of Magnetic Impediance analyzer. I am an enty level electronics person ,so need help to complete it.
The Analyser consist of a bridge of two coils in one arm and balancing potentiometer in other Arm. We have to feed a Regulated Sine wave of (0-5 Mhz), 1 V P-P ,and up to 10 ma Current to the bridge.
For this purpose I recently purchased EVAL AD5932(EVAL-AD5932EBZ). Further On running Eval Board( USB interface) ,I was able to get 70 mill volts Peak- to peak and regulated 0-10 Mhz; know my Question is:-
1. I need 0-10 millamp current for my coil ,so Can it be drawn from Eval Board or it will Damage the Board.I Tried searching inside datsheet but i could not figure out.
2. what is the maximum peak to peak voltage we can get fom eval board on USB interface?. Like can we get up to 1 V or 2 V peak to peak.if yes How?
3. should i use an Op-Amp for amplifying current and voltage ,I think it will not harm my Eval Board. Can you suggest suitable OpAmp.?I have LT1357CN8 ,LT1014CNG4, AD8684ARZ, AD524AD available ;Which one to be used or any other if you suggest.
Thank you fo your help.
