If you use this circuit as a preamplifier, then these two components must be left out. Here are some features of this IC. How can i calculate the ratios of a gear train correctly? Answer Questions Electrical network question to find current please help? I place a jumperwire from the voltage regulator’s third pin, to the IC’s sixth pin. Harm to minors, violence or threats, harassment or privacy invasion, impersonation or misrepresentation, fraud or phishing, show more.
Are you sure you want to delete this answer? This red wire goes to the supply voltage, in this case it will be 18 volts.
The next component is a microfarad capacitor, which is placed after this filter circuit, and if the filter circuit is left out then this capacitor is connected directly to the pin 5. Can i switch the D intergrated circuit for an LM integrated circuit? How do you integrate a 9v DC circuit into a device that already has a v AC power coming in to it? The black wire is connected to the ground rail.

I would choose the V version since the rambler is powered from a 9V source. I highly urc to make a test on a breadboard before making a PCB, so you’ll be sure it will work perfectly. Now, I place a jumper wire from the pin 4 to the ground rail. This green wire will be the output, it is connected to the negative terminal of the microfarad capacitor. A microfarad capacitor is also placed, these two capacitors will stabilize the supply voltage so the amp will work without noise. This integrated circuit is 386x used in small radios and DIY guitar preamp circuits, because it can also operate with just a 9 volt battery.
I take it you meant the Rambler 386, not the Gambler circuit: The DIP version doesn’t appear to be readily available. Another picofarad capacitor is placed between the pin 2 and pin 4 or the ground.
A 10 microfarad capacitor is placed between the pin 7 and pin 4, the negative side of the capacitor goes to the pin 4. The voltage gain of 20 will be more than enough for this circuit.
Thank you for watching, leave a like if you want to see more videos like this. Stuck Circuit Breaker Switch? In my homemade boombox in which 38d6 will use this preamplifier, the supply voltage is 18 volts so I will have to use a 9 volt regulator in order to operate this IC. This filter must be used only, when you use this amplifier to power 386c directly a speaker. Edit, answering your Additional Details: This IC is designed specially for battery usage, as you can see the quiescent current is very low, but this time for me it is not so important.
I made a drawing about the circuit so it is more simple to understand it.
I think the final result is very good, it looks nice and also sounds great. The yellow wire goes to the non-inverting input.

It is also important to make the leads short and the components should be close to each other, so it won’t pick up any noise. After placing the IC, I put the voltage regulator on the board.
Can i switch the 386D intergrated circuit for an LM386 integrated circuit?
Would recycle of the effluent improve the efficiency of continuous flow fixed bed carbon adsorption unit? This grey wire is used to connect the ground pin of the regulator to the ground rail. DigiKey carries the LM in two voltage flavors. Then when it doesn’t work, you will know it’s not because of a chip substitution.
Without the filter the amplifier can oscillate and heat up. In the description, it identifies the complete part number:
