Op amps transistor
Web12 de set. de 2024 · Operations amplifiers — op-amps for short, are integrated circuits, constructed mostly out of transistors and resistors. These integrated circuits multiply an … WebPlease have a look at the schematic. I use a trim potentiometer to set up the switch voltage so that it equals the zener voltage, in this case 3.3 volts. Then the Op Amp (741) switched to Vcc and drives the transistor (PN2222A) which switches on the 12V Relay and the buzzer. The Basis resistor is set in a way that I will have a Ic of around 150 mA.
