The TL431 is a full-fledged IC with a precision voltage level reference, a comparator ... In the simplest circuit, you could drive an LED with a TL431. Connect an LED and a current-limiting ...
028TSMC_COMP_01 is a comparator that compares a reference voltage to an analog input voltage and contains 8 input channels with a programmable threshold, implemented using 8-bit digital-to-analog ...
one red LED, and two 3.3 V Zener diodes. Begin by wiring up a 741 in open-loop mode as you did in a previous lab (Fig. 9.1(a)). With no negative feedback, the saturated output that results allows the ...
