I have to design a headphone amplifier circuit. There's no need connect any potentiometers to the output; there only needs to be a volume control on the input. So, I've got me an lm386 amplifier chip, and built the circuit 1 (amplify by 20 times) from the datasheet. The LM386 is a low-voltage audio power amplifier, designed to operate on 4V to 12V. LM386 IC's were used to make this. The thing I would be worried about here is impedance matching. LM386 is a low voltage audio amplifier and frequently used in battery powered music devices like radios, guitars, toys etc. 0,325W Audio Amplifier - The LM386 is a power amplifier designed for use in low voltage consumer applications. The Smokey Amp by Bruce Zinky was another design that used a 386 for some great sounds. 8UF R3 1K + C3 100UF/16v D1 LED C1 10UF The Information contained herein is supplied as a service to our customers and accuracy is not guaranteed nor is it definitive of any particular part or manufacturer. Generally speaking, the LM386 is a power amp and requires a line level signal (e. This circuit only need 10mA current with best voltage supply is 6-12VDC. The part has been replace in the v4 board currently shipping by discrete 2N3904/6 transistors. Tesseract can be heard on YouTube here:. You cannot receive a refund if you have placed a ShippingPass-eligible order. The 100 to 220 Ohm Resistor as Shown with "Headphone Use" in the Schematic Below, Reduces POWER to the Headset preventing Damage, But it also "Reduces Background Noise". LM386 mini audio amplifier circuit. This portable amp is an open hardware project designed by ElectroSmash using only free / open-source tools. 5W * 2 stereo amplifier. HT6872 is a low EMI, anti-cut top distortion, Mono Filter-Free Class D audio power amplifier. Discover a great selection of long-lasting amplifiers from top brands at the best price. The Bass Bump Headphone Amp is no exception, He built a motor control circuit that takes the audio output of an LM386 amplifier chip and translates it into drive signals for the motor. the amp fit nicely on an empty namecard box. Tone Control, shown in its most basic form in Fig. This circuit is based on single IC that is LM386 with few more components.
