voltage at the inverting input (Vb) of the op amp. The amplifier output will start to swing toward the negative supply rail, -VCC. When the magnitude of the Vb is equal to that of Va, the LED drive current will cease to increase. This condition forces the circuit into a stable closed loop condition.

Figure 14 shows how to interface two TTL circuits, using an optocoupler circuit that provides a non-inverting action. Here, the optocoupler LED and current-limiting resistor R1 are connected between the 5V positive supply rail and the output-driving terminal of the TTL device (rather than between the TTL output and ground), because TTL outputs can usually sink a fairly high …

9,484. Oct 16, 2014. #11. Crutschow's circuit is fairly linear because it uses a standard optocoupler with an LED and a photo transistor, and both halves share the same device physics. The Silonex part has a photo resistor, not a phototransistor, and …

possible to make a suitable amplifier using an op-amp and a couple of external power transistors, but we went with a simpler solution, and chose a chip that was specifically designed as an audio driver, the LM386, shown in Figure 1-5. Figure 1-5 – LM386 internal circuit and 8 …

audio opto isolator Hi, We have two channel audio to be seperated from the final stage audio amplifier. Now becase of different products the final power ampifier keeps on changing and we come across gounding loop/ humming noise. I know that optocoupler could be used to eliminate this. Does any one knows any good one for audio (analog). I am ...

Muting Circuits For Audio
https://www.sound-au.com/articles/muting.html
There is the option of using VCAs (voltage controlled amplifiers/ attenuators) to control the level of multiple channels of an audio system simultaneously. The circuit is shown in Project 141. This is easily muted by shorting the control voltage to the positive supply. The signal will be reduced to zero smoothly, with no distortion, clicks or pops.
