4557d

Hi everyone,

I'm designing a distortion pedal. In the schematic there's a dual opamp labelled 4557D. However, I can't find information on this device on the web. Does anyone know the complete name of this device or a possible replacement?

Thanx in advance for the help

op amp 4557d

For distortion pedal, you can use a generic dual op-amp like lm358, 1458 or tl082.
If you want low noise, use a tl072.

Generally, a guitard pedal is powered with a 9v battery and a rail to rail op-amp is a good choice.

Bye.
