Found in documentation from the 1980s, this circuit is used for resistive loads (incandescent lamps). The triac must be equipped with a heat sink.
In this application we show how to get tuning from 0 V to an LM350 regulator IC. The setting also...
This circuit uses the 741 Operational Amplifier to drive two LEDs. The LEDs indicate the signal of...
