bellychery05 Posted December 20, 2005 Report Share Posted December 20, 2005 I would like to construct a signal waveform generator.Here i contain an op-amp and a oscilator.please assist me on how i can get to design and construct it.I do appreciate your assistance.

audioguru Posted December 20, 2005 Report Share Posted December 20, 2005 I guess you don't want to use a precision but simple ICL8038, XR20x6 or MAX038 waveform generator IC like I used about 25 years ago.In Google, lookup Wien Bridge Oscillator circuit and you will find many circuits like the generator I built last year and similar to my very 1st project that I built more than 40 years ago.

Kain Posted December 20, 2005 Report Share Posted December 20, 2005 Audioguru, where do youfind datasheet for XR20x6? I tryed to google it, but nothing came up... ::) Quote Link to comment Share on other sites More sharing options...
audioguru Posted December 21, 2005 Report Share Posted December 21, 2005 Audioguru, where do youfind datasheet for XR20x6? I tryed to google it, but nothing came up... ::)Sorry, it is (was) XR2206 but I don't think it is made anymore. Its datasheet is here:http://www.datasheetarchive.com/semiconductors/download.php?Datasheet=2327414 Quote Link to comment Share on other sites More sharing options...
Kain Posted December 21, 2005 Report Share Posted December 21, 2005 Oh ok. It seems like the best of the 3 is the MAX038 anyways. Good thing I got it as sample some time ago ;D Quote Link to comment Share on other sites More sharing options...
Kevin Weddle Posted December 24, 2005 Report Share Posted December 24, 2005 My test lab uses an 8038. The output goes to an opamp followed by an emitter follower pole. That circuit really holds up to abuse! I waste transistors all the time, but that circuit never causes any trouble. Quote Link to comment Share on other sites More sharing options...
