5 volts audio amplifier ic
It commonly used in class-AB audio amplifier and can drive upto 50W music power into a 4 ohm speaker. TDA is a general-purpose 32W amplifier IC that can be used in stereo or mono audio design circuits. The amplifier can output upto 5A current to drive speakers without any damage. It can also handle short circuits in both AC and DC rail without killing itself. This makes it robust to be used in automotive audio designs. The TDA is breadboard friendly and hence can be easily tested using a breadboard.

10-Watt Audio Amplifier Using LM1875
Here is a simple watt audio amplifier using IC LM The IC has five pins and can deliver a maximum of watt output power depending upon the supply voltage and load. The circuit diagram of the audio amplifier is shown in Fig. Connect 15V battery and switch on S1. You should hear amplified sound in speaker LS1. Use a watt soldering iron for soldering LM and other components. A 2-pin connector should be used for input and output connections to make the prototype safe and clean.
Use a suitable heat-sink for LM to prevent its overheating. A PCB layout for the amplifier is shown in Fig. After assembling the circuit on the PCB, enclose it in a suitable box.
Fix LS1 on the rear side of the box. For testing the circuit, connect a 6V battery to this circuit along with an 8-ohm, watt speaker. Take a metal screwdriver and gently touch at the input terminal. If your prototype is working, you will hear a humming sound from the speaker. You may connect a kilo-ohm potmeter between audio input and ground and middle pin of potmeter to pin 1 for volume control.
Your circuit is now ready to use. You can use the power supply from a 5V to 15V battery, which will give you clear and noise-free audio signal output. Raj K. Gorkhali is a regular contributor to EFY. His interests include designing electronics circuits. This circuit is not working. The circuit in the datasheet has a voltage divider consisting of two resistors but here only one resistor is connected at input pin 1.
This circuit is not working as there should be a voltage divider network at pin 1 of the IC. I have constructed the circuit according to datasheet and it gives only 2 Watts max at 22 Volts, 2 Amp transformer.
Anirvan was correct to mention that there is a voltage divider at pin 1. The schematic on P3F2 uses a different topology than the schematic here. Do not try to combine them, or add a second resistor like the datasheet except to the schematic on this page , or it will not function.
The schematic here uses a voltage feedback topology to set the gain whereas the P3F2 schematic uses a resistor shunted between a voltage divider between the supply voltage and ground to set the gain with that second resistor you refer to. This guy need to go back to school, this circuit will NOT work as others have said, for a single ended supply the input needs to be biassed to half the total supply so the output at pin 4 is around The prototype sent to us by author was working fine.
However, for better performance your point is correct. Its always better to follow the datasheet. Waiting reply from author.

Automotive audio power amplifier ICs
BA is a stereo amplifier IC with a lot of good features like thermal shut down, standby function, soft clipping, wide operating voltage range etc. Setup and working of this stereo power amplifier circuit is somewhat similar to the BA based stereo amplifier circuit published previously. C2 and C6 couples the amplifiers left and right power outputs to the corresponding loud speakers. C1 and C5 are bootstrap capacitors. Bootstrapping is a method in which a portion of the amplifiers is taken and applied to the input. The prime objective of bootstrapping is to improve the input impedance. Networks R1,C3 and R2,C7 are meant for improving the high frequency stability of the circuit.

Your question might be answered by sellers, manufacturers, or customers who bought this product. Please make sure that you are posting in the form of a question. Please enter a question. Please use 2. Do not use AC power supply or power supply higher than 5. The shared power supplies interfere with each other. Unreasonable wiring when installed Second, the power amplifier board sound is small? The speaker has no box body exposed. When the sound wave is short-circuited, it will feel small.
5W Stereo Audio Amplifier
An amplifier , electronic amplifier or informally amp is an electronic device that can increase the power of a signal a time-varying voltage or current. It is a two-port electronic circuit that uses electric power from a power supply to increase the amplitude of a signal applied to its input terminals, producing a proportionally greater amplitude signal at its output. The amount of amplification provided by an amplifier is measured by its gain : the ratio of output voltage, current, or power to input. An amplifier is a circuit that has a power gain greater than one.

Due its internal elements this circuit requires few external resistor and capacitors only. IC NS pin 1 is called as SD pin, this amplifier enters into shutdown mode when a high level is applied on SD pin, there is a switch connected between pin 1 and ground it represents low level if the switch gets open then high level is applied. Pin 2 is called as BYP, Bypass capacitor pin which provides the common mode voltage. Pin 4 is -IN Negative input of the first amplifier, receives the audio input signal through coupling capacitor C1 and R1 Resistor.
