That should work. You should make sure you have a ground plane and chest don’t know is how quiet the 5V to +\-15 chip you are using is ?

Here's a version of a USB powered Alice.? Comments welcome since my ability to make errors is well known.

Hello, I've drafted up a DIY design that I think could work to drive an electret capsule like the TSB-2555B through the use of a DC-DC converter () to derive a stepped up voltage from the 5V supply rail of a .?
The generated voltage of the microphone is fed into an amplification circuit from the?
Presented below is the proposed amplification scheme:
<dummyfile.0.part>
Similar to the aforementioned OPA-Alice circuit, the amplifier to be used is planned to be the OPA1642.
The USB soundcard to be integrated to the design utilizes a CM108 IC with an input range of 2.88 V pk-to-pk and a default input signal gain stage of 20dB (gain of 10).
I am relatively new to the design of microphone circuitry and this design is heavily inspired the by videos and instructables from DIY Perkz and DJJules.?
I would like to ask for advice regarding the design choices made and the validity/viability of the proposed design.
