LM348 substitute LM348 substitute sanvik (Electrical) (OP) 21 May 15 13:29 If we replace LM348 Op-Amp with TL074 Op-Amp, this is a direct substitute, and no changes are needed in passive components in circuit? RE: LM348 substitute IRstuff (Aerospace) 21 May 15 14:16 Hypothetically, yes. But without a detailed analysis of what each op amp is doing in the circuit, it's not really possible to say TTFN FAQ731-376: Eng-Tips.com Forum Policies [IMG http://tinyurl.com/7ofakss] Need help writing a question or understanding a reply? forum1529: Translation Assistance for Engineers Of course I can.

So is it OK? RE: LM348 substitute felixc (Electrical) 4 Aug 15 02:24 Why are you looking to replace he LM348? Your circuit seems rather basic, but layout issues may lead to oscillation or crosstalk if you use ICs with higher bandwidth. Instead of a TL074, what about an LF444? It is designed to replace the LM348, with similar characteristics but with a reduced power consumption.
