can any1 plz tell me what other precision opamps can be used instead of LT1013 AND LMC662
AND ALSO WHAT TRANSISTOR CAN BE USED IN PLACE OF 2N4401 ANS 2N3904.......
Your questions are rather vague. What parameters fit your needs in an op amp? What type of design are you trying to complete? Do you have a circuit you can post? Etc. The same basic questions apply to your transistor question.
