Question

Choose what range of voltages at Vin will turn ON the LED. 12V 1k Vin * 5V LM339 Select one: a. Vin > -5.0V b. Vin < +5.0V O c. Vin > +5.0V d. Vin <-5.0V

Answer 1

Given Circuit • 124 Vin I |к (M3 39 5V- 2 The (M339 is a voltage comparator. If Vin <5v, Then Current will be in the direction of I, LED will be on. - In the Circuit. given, If A=o, Bao A-1, B2o Q=0.(Trankisto) is OFF) Q = 1 (Tansists, 18 on) Q=1 (Transiste is on Qal (Transiste is on A=0, Bal Azl, B=1 The Circuit is or gate. given
