He said he was using a bjt 555. When low, those will output nearly to ground, but when high, they're ~1.2v or so less than Vcc due to the Darlington follower.@Sgt: Why did you suggest connecting a pull-up on the LMC555 and on which one? U1 I assume? If the DC offset at the output is 0.4V from the 555's GND then this value is inside specs, at least according to the datasheets I just had a look at. Or am I refering to the wrong schematic ?
Use an XR-2206 and make life easy:Good day,
PLEASE HELP
I have a project to simulate and build a low cost function generator. This can be either using Op amps, IC timers or Function Generator IC's.
They are being used as a pair of Schmitt-trigger inverters wired in series.What i want to know relates to the use of the two CMOS chips to generate the square wave. Is there a specific name for its configuration?
