LM193-N, LM2903-N, LM293-N, LM393-N SNOSBJ6E – OCTOBER 1999 – REVISED MARCH 2013 www.ti.com APPLICATION HINTS The LM193 series are high gain, wide bandwidth devices which, like most comparators, can easily oscillate if the output lead is inadvertently allowed to capacitively couple to the inputs via stray capacitance. This shows up only during the output voltage transition intervals as the comparator change states. Power supply bypassing is not required to solve this problem.
