High gain Mic Preamplifier

i think i've got it
What do you think?

I need something similar for the photo diode sensor. From what i can find on the internet, i don't understand well the trans impedance amplifier, so maybe some one will explain it to me on a beginner level. the link from old post https://www.electro-tech-online.com/attachments/canon_eos450d_remotecontrol-jpg.34745/

Good.
You have a sensitive audio circuit.

A transimpedance amp converts the extremely low current from the photo-diode to a voltage.

Hello Audioguru,

This is the trans impedance amp that i figure it out so far, do you think will work for my needs?
