I'm building an auto-wah pedal and I was planning on using the NE5532 dual op amp instead of the LM358 dual op amp. Will this make much of a difference?
Their spec's are completely different:
1) The lousy old LM358 works from a supply as low as 3.0V but the NE5532 needs a minimum of 6.0V.
2) The LM358 has inputs that work at 0V and an output that goes very close to 0V, but the NE5532 has inputs that do not work when they go below 3V and has an output that goes down to only 1.5V.
3) The LM358 has negative input bias current but the NE5532 has positive input bias current.
4) The LM358 has open inputs but the NE5532 has diodes across the inputs.
5) The LM358 has poor high frequency response but the NE5532 has excellent high frequency response.
6) The LM358 has a lot of noise and distortion (to make fuzz?) but the NE5532 has low noise and has very low distortion.
