I built a hobby mic op-amp circuit as described here:
It gave me a pretty ok result: Now I replaced LM358 with LME49710. The circuit is the same, except from the wiring to the LME49710 pins (LM358 pin 1 is the output while it's pin 6 on LME49710, VCC also moved from pin 8 to 7, the rest are the same)
That doesn't look right and doesn't sound right. A lot of noise is added, and the audio is less amplified and hardly heard over the noise.
- What are LME49710 characteristics that makes it less suitable for this circuit?
- Is there a simple way to change the circuit and make it work better with LME49710?
