I agree with Rob, who says that 17mV offset voltage drift is caused by the 5V voltage regulator itself. Well, I was rather hoping that Jayachandran would confirm how his circuit is powered and if he had indeed overlooked the regulator drift. As the PWM output is taken from a CMOS inverter, it could be an option to feed just that IC from a very stable 5V source. An LP2980 would do nicely here. The only drawback might be the 5-pin SOT-23 package. Rob. |
