I am looking for datasheet of these opamps but I couldn't find any. I want to replace them with BB or 6172 but I want to know the datasheet before changing. Can anyone help me? what are websites that contain datasheet for free view or download?
1. C358HA
2. D4094G
3. 4570
4. 2903 (JRC)
New chips would be 2604, 2134, 627&637 (with adapter), 6172, AR8066.
Thank you for your inputs.
