Please help me to reduce the number of components in this circuit.
I experienced it at the time.I worked but not at an acceptable level.
-The place to enter the PCB is small.
-I would like to use the electret microphone
- I use PIC12F675 with A/D (Edit: I misspelled the name of the IC)
For example there are PIC16F1769 with op amp internally connected. But it is big enough for the purpose.
-I want to get out of the schematic to tI misspelled the name of the IChe two transistors(BC847)
---maybe to find a microphone with the desired amplification in the same case
---Or to use the A / D input (in PIC12F675) 10 bit 0...5V, but the signal at the output of the unamplified microphone would be too small ....maybe.....10mV/Pa
- 12F675 is doing simultaneously other task, so I do not give up on it
