Many times we have been asked about an amplifier that can be powered with the computer source to amplify this. We have also seen the need for an amplifier that can be transportable everywhere and that provides an acceptable power service. Thinking about filling these expectations, we present a 20W stereo amplifier (10W per channel)…
The amplifier uses a hybrid two-channel IC STK4241-II manufactured by SANYO. Immediately, it is worth noting that the pinout of the STK4241 is compatible with such chips as the STK4201V-series (THD = 0.08%) and the STK4141-series (THD = 0.02%). In the archive for download you will find 5 technical descriptions (DATASHEET) on STK4201, STK4211, STK4221,…
A simple all-in-one TBA820M from the past that many of you know and experience. Despite its small size, it accomplishes great work from its height according to its time, its price is cheap, the area it covers is small and its working tension is quite flexible. I have tried to make the two circuit boards…
Mono power module, based on LM3886 application. He enjoys very high popularity and good reputation even among audiophiles who are “overly sensitive to everything that is integrated”. The LM3886 integrated circuit is based on bipolar transistors. It is equipped with protection circuitry for overheating, overload, and a very useful muting circuit for switching on and…
TPA3116 Class D Amplifier Circuit A small class-D mid-range stereo headset that will be used in car headphones, active speakers, or PC-audio. The amplifier module is based on the TPA3116 circuit comprising two bridged power amplifier channels with common switching, muting and protection circuits. TPA3116 Circuit schematic The TPA3116 power amplifier schematic diagram. The U1…
LM4952 It is not always necessary to have a high power audio amplifier. It is enough to power the small speakers with much less power. The presented amplifier meets this condition. It has a power of 2 × 3 W / 4 V, and additionally allows electronic volume control. LM4952 The module is based on…
Guitar Amplifier circuit the signal is directed to the tip of the TDA2050. The output power is 25 W with a load of 4 ? (17 W at 8 ?). This block is equipped with an additional “CD / MP3 Player” input and three “Slave Out” outputs (for other terminals or recording equipment), “Headphones” (for…
The amplifier module is based on the TPA2005 chip with a bridged TPA2005 power amplifier capable of delivering up to 8V of almost 1.4W at 5V. Thanks to the small operating voltage (2.5V), it was possible to power the typical Lipo 14500 without additional boosters . The audio signal from the IN jack is fed…
AD8532 Small, high-quality headphone amplifier that works with 32? … 100? low impedance headphones. Ideal as an audio supplement. Headphone amplifier with low-noise, low-voltage AD8532 operational amplifier up to 250 mA. Low-noise power supply with ADP7104 regulator. AD8532 headphone amplifier circuit schematic the power supply input signal from the IN jack is fed to a…
Amplifier 4×60 Watts. To its solution was first selected integrated circuit LM3886T. The proposal continued the calculations and the election of the additional components of the integrated circuit and the design of printed circuit connections. To the end amplifier was also designed system of active cooling. In the fourth chapter was made the proposal of…
