STK4050V Power Amplifier Circuit

The project is based around the hybrid integrated circuit power amplifier with STK4050 manufactured by Sanyo to build a low clatter mono audio amplifier with complete peak quality. Explanation The project has a ceiling output power of 200W while incorporating a volume control. The power supplyused participating in the circuit is an on-board type and as of this, barely a hub tapped transformer is considered necessary in place of the powering of the circuit. The sound has a very fine quality and it can stay proven once used in to your place theaters, in computers, and other audio equipments which can as well be used being subwoofer amplifier. On behalf of water down-type audio sets, it can be considered as a compact package. The leg generated arrived thin-type audio sets is being discrete certainly with a good heatsink design. nearby may possibly live reason someplace a shock din may be encountered especially for the period of switch ON and switch inedible. This can be summary by only if a constant current circuit. The design of the circuit can be tailored used for sinking occurrence of thermal shutdown, brief circuit protection for oodles, shock racket muting from exterior power supply. The load resistance besupposed to arrange 8 Ohms profit with 55K Ohms input impedance.

LM317 Amplifier Circuit

You probably know with the purpose of LM317 IC is used being an changeable voltage manager, but did you know it can take place used as an audio amplifier? This is a taste A audio amplifier built with LM317 so as to delivers a utmost 1W audio power. Manipulate a worthy heatsink pro the LM317 IC and adjust the 5K inconsistent resistor so with the aim of you allow 4.5V on 10Ω resistor (otherwise LM317 pin 2, Vout).

3 Watt stereo amplifier circuit

3 Watt stereo amplifier circuit using MAX 7910 IC. The MAX9710 a stereo audio power amplifier IC capable of delivering 3Watts of out put to 4 Ohm loads. MAX9710 can be operated from a single 4.5V to 5.5V power supply , makes it ideal for hand held applications.The IC for 3 Watt stereo amplifiercircuit also features thermal overload protection. This 3 Watt stereo amplifier circuit is suitable for small power audio devices such as radio sets and portable CD players. 5 V DC power supply is used for powering the 3 Watt stereo amplifier circuit. 6V battery with an IN 4007 diode series to the positive terminal of it can also be used instead of 5 V DC supply. The 3 Watt stereo amplifier circuit will get a supply voltage approximately 5 V after 0.7 V voltage drop across diode.

BTL Stereo Amplifier TDA7052

This is BTL stereo power amplifier with basic amplifier on IC TDA7052 / TDA7053

170W power amplifier LM4651 and LM4652

170 Watt power amplifier is a power amplifier that is built by IC LM4651 and LM4652.

Part of this power amplifier driver using the LM4651 IC designed specifically for the purpose of the class AB amplifier driver with short circuit protection feature, containing under voltage, thermal shutdown protection and standby functions. Section 170 Watt power amplifier using LM4651 IC with a MOSFET power amplifier is equipped with temperature sensors that will be used by IC LM4651 as controlnya thermal signal. IC IC LM4651 and LM4652 are designed specifically to each other in pairs to create a class AB power amplifier with protection features are detailed. Detailed series of 170 Watt power amplifier can be seen in thethe following figure .

170W power amplifier LM4651 and LM4652
