Car Amplifier Circuit 2 x 30 W stereo

General description:
The TDA8566 is an integrated class-B output amplifier which is available in several packages. TDA8566TH is contained in a 20-lead small outline plastic package. The TDA8566TH1 is a 24-lead small outline plastic package which is pin compatible with the I2C-bus controlled amplifier TDA1566TH for one board layout. TDA8566Q is a 17-pin DIL-bent-SIL package. The device contains 2 amplifiers in a Bridge-Tied Load (BTL) configuration. The output power is 2 × 25 W in a 4 Ω load or 2 × 40 W in a 2 Ω load. It has a differential input stage and 2 diagnostic outputs. The device is primarily developed for car radio applications.

Features:

• Differential inputs
• Very high Common Mode Rejection Ratio (CMRR)
• High common mode input signal handling
• Requires very few external components
• High output power
• 4 Ω and 2 Ω load driving capability
• Low offset voltage at output
• Fixed gain
• Diagnostic facility (distortion, short-circuit and temperature pre-warning)
• Good ripple rejection
• Mode select switch (operating, mute and standby)
• Load dump protection
• Short-circuit proof to ground, to VP and across the load
• Low power dissipation in any short-circuit condition
• Thermally protected
• Reverse polarity safe
• Protected against electrostatic discharge
• No switch-on/switch-off plops
• Low thermal resistance
• TDA8566TH1 is pin compatible with TDA1566TH

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.
