lm393, lm293, lm2903, lm2903v, ncv2903 http://onsemi.com 5 applications information these dual comparators feature high gain, wide bandwidth characteristics. this gives the device oscillation tendencies if the outputs are capacitively coupled to the inputs via stray capacitance. this oscillation manifests itself during output transitions (v ol to v oh ). to alleviate this situation, input resistors < 10 k should be used. the addition of positive feedback (< 10 mv) is also recommended. it is good design practice to ground all unused pins. differential input voltages may be larger than supply voltage without damaging the comparator ?s inputs. v oltages more negative than ? 0.3 v should not be used. figure 8. zero crossing detector (single supply) figure 9. zero crossing detector (split supply) figure 10. free ? running square ? wave oscillator figure 11. time delay generator figure 12. comparator with hysteresis 10 d1 prevents input from going negative by more than 0.6 v. r1 + r2 = r3 r3 r5 for small error in zero crossing. v in 10 k d1 r1 8.2 k 6.8 k r2 15 k r3 +15 v 10 m r5 220 k r4 220 k lm393 v in(min) 0.4 v peak for 1% phase distortion ( ). +v cc 10 k v in -v ee v in v in(min) v cc v o - v ee lm393 - + lm393 51 k 51 k 51 k r l 10 k v cc v cc v cc v o v o t 0 1.0 m 0.001 f - + lm393 v cc v cc v o v in v o + v ref v ref v ref 0 0 0 v c t o t ``on'' for t t o + t where: t = rc n ( v ref v cc ) r r l v c c lm393 - + r s v cc r l v ref r1 r2 r s = r1 | | r2 v th1 = v ref + (v cc -v ref ) r1 r1 + r2 + r l v th2 = v ref - (v ref -v o low) r1 r1 + r2 r1 t - + lm393
