Hi how are you? im martin from argentina, this is exactly what i need, it sounds excelent, can you share me the schematic of this design? I have a few ina217 in my box and it would be awesome give them some use
@Armasargentinas Hi, I really just used the schematic from the INA217 datasheet with the minor modifications mentioned in a comment before. I'll send you a PM with a link to the datasheet...
The preamp sounds good. I bought 4 such ICs and would like to build mic and electric guitar preamps. The point is that all schematics I found are differential input while my microphone is not XLR but a plain signal + ground; guitar output is the same in this regard. How do you connect?
if you power the preamp with four 9V batteries, the shown circuit is all you need. I used the schematic from the INA217 datasheet (FIGURE 4), just without the phantom power, the optional DC output control loop (replaced by a 470uF cap) and without the 1n4148 diodes. I have built a powersupply for this circuit too, which needs more space than the preamp itself. :D I will send you a PM with a link to the datasheet...
Brilliant! great sound. Any possibility of sendin the schematics ? I'm an electronics hobbyist/musician. thanks!

Which powersupply you built for ina217? Do you have shematic (powersupply) for it?

can you post the schematics? dont you need more caps and resistors than shown at 0:20?

Wow, is this recorded with the pre? Sounds great!

Yes it is recorded with the INA217 preamp straight into the line in of my notebook
