From: Gone Fishin' on 6 Apr 2010 18:29 This TI app note describes a single-supply wien bridge oscillator, which helps me with a partial solution: < http://www- k.ext.ti.com/SRVS/Data/ti/KnowledgeBases/analog/document/faqs/sscco2.htm> The note does not describe specific op amp P/N's. Should I limit my design to a single-supply op amp? Or can a dual-supply op amp and a single supply be used here? Thanks.

Does it have to be centered around zero volts? Does it have to be symmetrical? JF |
