PC74F132D PC74F132D PC74F132D Datasheet The modulated signalis coupled by windings W6 and W7 to two matched demodulators-one in the input stage and one in the output stage-which generate identical voltages at their outputs, pins 10 and 1 1 (Voltages identical with respect to their respective commons, pins 3 and 17). In the input stage the input amplifier, Ai, the modulator and the input demodulator are connected in a negative feedback loop. This forces the voltage at pin 6 (connect as shown in Figure l) to equal the input signal voltage applied at pin 7. Since the input and the output demodulators are matched and produce identical output voltages, the voltage at pin 11 (referenced to pin 17, the output common) is equal to the voltage at pin 10 (referenced to pin 3, the input common). In the output stage, output amplifier A2 is connected as a unity gain buffer, thus the output voltage at pin 15 equals the output demodulator voltage at pin 11. The end result is an isolated output voltage PC74F132D PC74F132D PC74F132D Price
