LM386N Audio Power Amplifer Amplifier 1x2W

LM386N general description:

The LM386 is a power amplifier designed for use in low voltage consumer applications. The gain is internally set to 20 to keep external part count low, but the addition of an external resistor and capacitor between pins 1 and 8 will increase the gain to any value up to 200. The inputs are ground referenced while the output is automatically biased to one half the supply voltage. The quiescent power drain is only 24 milliwatts when operating from a 6 volt supply, making the LM386 ideal for battery operation. LM386N Audio Amplifier 1x2W

LM386N features:

NCP2890 Audio Amplifier 1W

NCP2890 general description:

The NCP2890 is an audio power amplifier designed for portable communication device applications such as mobile phone applications. The NCP2890 is capable of delivering 1.0 W of continuous average power to an 8.0 BTL load from a 5.0 V power supply, and 320 mW to a 4.0 BTL load from a 2.6 V power supply. The NCP2890 provides high quality audio while requiring few external components and minimal power consumption. It features a low−power consumption shutdown mode, which is achieved by driving the SHUTDOWN pin with logic low. The NCP2890 contains circuitry to prevent from “pop and click” noise that would otherwise occur during turn−on and turn−off transitions. For maximum flexibility, the NCP2890 provides an externally controlled gain (with resistors), as well as an externally controlled turn−on time (with the bypass capacitor). Due to its excellent PSRR, it can be directly connected to the battery, saving the use of an LDO. This device is available in a 9−Pin Flip−Chip CSP (standard Tin−Lead and Lead−Free versions) and a Micro8 package. NCP2890 Audio Amplifier 1W

TDA8560Q Audio amplifier 2x40W

TDA8560Q general description:

Unfortunately, some of the proposed scheme in the network and even a scheme recommended by the developer (Philips), fail to achieve the desired result. As an example of how not to suggest that you include the TDA8560 material published on Online Soldering: Car Amplifier 2x40 Watt (I should note that everything except the input circuits and the number of points on diet, still deserves attention). the initial inclusion of IMS (at power up, the load is connected and there is no input signal) can throw you into a state of perplexity / mild shock (it depends on the degree of hope is for your TDA). Chip is unstable, there are noises when the input signal is amplified last weakly and passed with distortions. IC bypass surgery fixed resistor at the input, the other measures in consultation with the source device does not help. Why and what to do? Really caught Palen chip and will have to buy a new one? Not so fast! The fact that Philips did not include measures to prevent the self-excitation of the IC, but I think they know about it, but do not tell anyone (not good, gentlemen!) Rid chip excitement can (and should) in a way that is not described here. This is so far, my little secret. Usually TDA8560 include approximately recommend the following scheme: TDA8560Q Audio amplifier 2x40W

Power Amplifier 60 Watt supply voltage 30 - 60 Volts

Power Amplifier 60 Watt supply voltage 30 - 60 Volts

This is a simple and low cost 60W power amplifier. The optimal supply voltage is around 50V, but this amp can work from 30 to 60V. The maximum input voltage is around 0.8 - 1V. As you can see, in this design the components have a big tolerance, so you can build it with almost any components that you can find at home. The output power transistors can be any NPN types, but do not use Darlington types.

Capacitor C1 regulates the low frequencies (bass), as the capacitance grows, the low frequencies are getting louder. Capacitor C2 regulates the higher frequencies (treble), as the capacitance grows, the higher frequencies are getting quieter. 

This is a class B amplifier, this means, that a current must flow through the end transistors, even if there is no signal on the input. This current can be regulated with the 500 Ohm trimmer resistor. As this current increases, the sound of the amplifier is better, but output transistors are dispatching more heat. If the current is decreased, the transistors are dispatching less heat, but the sound quality is decreased.

TDA1566 Audio Amplifier 2x46W / 1x92W

TDA1566 general description:

The TDA1566 is a car audio power amplifier with a complementary output stage realized in BCDMOS. The TDA1566 has two Bridge Tied Load (BTL) output stages and comes in a HSOP24 or DBS27P package.

The TDA1566 can be configured in a single BTL mode and drive a 1 Ω load. For the single BTL mode it is necessary to connect on the Printed-Circuit Board (PCB) the outputs of both BTL channels in parallel.  TDA1566 Audio Amplifier 2x46W / 1x92W
