TDA chips. My rating of 45 amplifiers from weak to the most powerful 100W

In household electronics, to amplify low frequencies or sound, ready-made amplifiers made in one microcircuit are used. In this article, I have collected 45 microcircuits of the popular TDA series of low-frequency amplifiers and made a simple rating from the lowest-power to the most powerful microcircuits in various cases.

Microcircuits in the SIL9 case. Such microcircuits can be soldered from old TVs on a kinescope. The lowest-power is TDA1013B, has an output power of 4 W with a supply of up to 40 V. All microcircuits in the photo have a single-polar power supply. The most powerful tda7266l with a sound power of 7 W

In the TO-220-5 case, these are five-pin amplifiers. The most common TDA2003, was used in cheap cassette tape recorders in the 90s. Also, there was earlier and maybe even today the TDA2030A amplifier is widely used, it has an output power of 18 W

Next are the microcircuits in the common MULTIWATT case. Such amplifiers were installed in car radios of the 90s and early 2000s. Probably from them came this inscription on the radio case: 25W + 25W SUPER STEREO and so on. All microcircuits, except for the output power, are also observed by the coefficient of nonlinear transformations, by power supply - unipolar or bipolar and other characteristics and functions

Amplifiers in DBS case. They can be unsoldered from CRT TVs or car radios. The most popular is TDA7057AQ, 8+8W and requiring single-polar power supply. You can find out about this if the table indicates +/- Volts. The most powerful are TDA7294 and 7293, with a power of 100W at the output, the output stage is made on field-effect transistors, in the datasheet this is indicated as DMOS

TDA8927J has an output of 80+80W and operates in D-class. Low-frequency amplifiers can also be made from frame scan microcircuits, they are cheaper but I have not tested the quality

Three microcircuits, which I think I soldered from TVs

Next comes the "heavy artillery". Of the four microcircuits in the photo, only one requires bipolar power supply, this is the tda8920bj 100+100W microcircuit and operates in class D. All other microcircuits require a unipolar voltage source of 6-18V

Microcircuits in a different case than in the photo also require a single-polar power supply except for the TDA 7490L, this is 20+20W operating in class D. Also, the power can be specified as when connected using a bridge circuit, as a result, 20W on one channel and +20W in the other channel turn into 40W in one channel

There is another microcircuit - "chocolate bar" TDA8588. Four outputs of 50 W and many different "bells and whistles" used in more modern car radios
