Classroom demonstration circuit for comparator action uses transistor to amplify output of one section of RS339 quad comparator, to boost output currnet rent enough for driving 60-mA lamp. Lamp comes on when voltage at movablearm of 500K pot is greater than half of supply voltage.—F.M. Mims, Integrated Cireuit Projects, Vol. 6, Radio Shack, Fort Worth, TX, 1977, p 33-41.
