Velleman MK136 Super Stereo Ear

the following program is brought to you by element14 the electronics community where you can connect and collaborate with top engineers from around the world join now at element14.com slash presents hi and welcome back to the learning circuit where we learn about basic electronics today we're going to build a kit that uses an op-amp to boost sound element m'kay 1:36 super stereo ear [Music] this kit uses an any five five three two op-amp so the IC contains two op amps on the pin out you can see pins four and eight are the supply voltage pins the inverting and non-inverting inputs and the outputs of each op amp each op amp amplifies the signal from one of the two microphones and outputs the signal to a phone jack looking at the schematic we can see that each op amp has a near isolated circuit and that the two circuits are identical the signal comes into each microphone is processed throu
