The TDA2006 is a monolithic integrated circuit in Pentawatt package, intended for use as a low frequency class "AB" amplifier. At ±12V, d = 10 % typically it provides 12W output power on a 4Ω load and 8W on a 8Ω . The TDA2006 provides high output current and has very low harmonic and cross-over distortion. Further the device incorporates an original (and patented) short circuit protection system comprising an arrangement for automatically limiting the dissipated power so as to keep the working point of the output transistors within their safe operating area. A conventional thermal shutdown system is also included. The TDA2006 is pin to pin equivalent to the TDA2030
This audio amplifier Circuit is a class-B audio power amplifier using a TDA1010. It is easy to construct and has only a few external components. The circuit is designed with short circuit and thermal protection. It can drive loads as low as 1.6 ohm and is capable of deliveringover 10 watts from a 16 V DC power supply.

This is a 22 Watt car stereo audio amplifier. The circuit is based by a single IC TDA1553 with some external components, this IC will handle your stereo car audio system. The IC TDA1553CQ contains 2×22 W amplifiers with differential input stages and can be used for bridge applications.. The gain of each amplifier is fixed at 26 dB. The device is primarily developed for car radio applications.
DA1553CQ IC PinningNote:
When a short-circuit to ground occurs, which forces a DC voltage across the loudspeaker of >= V, a built-in protection circuit becomes active and limits the DC voltage across the loudspeaker to <= V. Pin 12 detects the status of the protection circuit (e.g. for diagnostic purposes).
If any output is short-circuited to ground during the standby mode, it becomes impossible to switch the circuit to the mute or operating condition. In this event the supply current will be limited to a few milliamps.

Rangkaian TDA 7053 Stereo Audio AmplifierThe TDA7053 Integrated Circuit does nearly all the work, so there are only a few external components. C1 and C2 provide power supply decoupling or filtering. R1 and R2 provide a DC ground reference for the input signals, and may be increased if your source requires a higher load impedance. Do not use more than 100k ohms.
Since the amplifier circuit in BTL configuration, the outputs are floating with respect to ground. Therefore NO output leads should be connected to ground. The Philips data sheet contains all the necessary information about the TDA7053.

TDA1554 IC Rangkaian TA8215 Car Audio Amplifier
This is circuit of 15W BTL stereo channel audio power amplifier based IC TA 8215 developed by Toshiba. In this power amplifier circuit, two TA 8215 ICs are used. This is for obtaining four channels that is two channels from each IC. TA 8215 is an IC with power amplifier stages and preamplifier integrated inside it.
The power supply required for this amplifier is single 12 V DC supply. The maximum output power delivered from each channel of this amplifier is 15 W to a 4 ohm speaker and hence the name 4×15 W power amplifier.
The power supply required for this amplifier is single 12 V DC supply. The maximum output power delivered from each channel of this amplifier is 15 W to a 4 ohm speaker and hence the name 4×15 W power amplifier.
TA8215 ICR1 with R2 forms a voltage divider that attenuates the input signal by 24dB. Considering the chip's 50dB gain, that still leaves 26dB overall gain, slightly more than enough to fully saturate the amplifier when the sound card works at maximal output. C1 blocks DC at the preamplifier input. C2 is the ground return of the feedback circuit. These two capacitors need to be in the ratio shown, in order to suppress switching clicks when powering the circuit on and off. The output pins 15 and 16 are connected directly to the speaker, while C7, R6, C8 and R7 provide the proper load phase shifting to avoid high frequency instability.
The power supply is decoupled with a rather small 100uF capacitor. That's enough for higher frequency decoupling, and at lower frequencies anyway the large capacitors in the PC power supply are fine. Pins 10 and 17 supply the power amplifiers, while pin 9 provides power to the pre stages. This power is filtered by C3. The power control pin 4 allows to shut down the amplifier, an option not used here, so it's tied to 12V. Pin 1 is a muting input, also not used, and left open.

Rangkaian 12 Volt Audio Amplifier
This circuit power amplifier was deliberately designed using no ICs and in a rather old-fashioned manner in order to obtain good harmonic distortion behavior and to avoid hard to find components. The amplifier(s) can be conveniently supplied by a 12V wall plug-in adapter. Closing SW1 a bass-boost is provided but, at the same time, volume control must be increased to compensate for power loss at higher frequencies. In use, R9 should be carefully adjusted to provide minimal audible signal cross-over distortion consistent with minimal measured quiescent current consumption; a good compromise is to set the quiescent current at about 10-15 mA.To measure this current, wire a DC current meter temporarily in series with the collector of Q3.

This is circuit amplifier contains only an op-amp and four transistors (easily available from your electronics junk box). the op-amp used is uA 741 which produces the required gain.The four transistors are wired as complementary Darlington’s which produces the drive for the speaker.
Skema Rangkaian 12 volt Amplifier
The voltage drop across the resistors R2 and R3, are used as the input of the Darlington pairs . As the input current to the op-amp depends on the level of the signal op amp is amplifying the voltage drop across the resistors R2 and R3 will be proportional to the input signal.These voltage drops are given to the base of Darlington pairs. The amplification is stabilized as a result of the negative feedback from the junction of collectors of Q2 and Q4. The theory may seem little awkward for you.But its working good.Such a simple but stable circuit as this can produce a reasonable output of 12W on a 4 Ohm speaker.
IC Op-Amp UA741
The UA741 is a high performance monolithic operational amplifier constructed on a single silicon chip. The high gain and wide range of operating voltages provide superior performances in integrator, summing amplifier and general feedback applications. The internal compensation network (6dB/ octave) insures stability in closed loop circuits.
