TDA8920 PDF

Several protections and diagnostic options are incorporated in this design. The is a bipolar IC used for preamplifiers that receive signals in infrared remote control systems. These ICs consist of a first-stage amplifier, limiter amplifier, band-pass filter, band elimination filter, signal waveform detection circuit and waveform shaping circuit. It has three separate, bit, pixel inputs, one each for red, green, and blue video data. A single 5. Successive approximation conversion is performed by two monolithic dice housed a 28 lead package.

However, in the foregoing, there are various suggestions regarding enhancing its output power. If built into a bridge configuration and driving an 8 ohm speaker, the peak power for such a configuration is 5 x 5 x 8 i. Such a configuration works well in practice, both with split rail power supplies and with single rail power supplies. My experience with many many TDA that I have used, is to limit the total supply rail to 45 volts maximum providing a few volts safety margin. That is not even as good as the TDA Too bad ST discontinued them, but with all the fakes it must have diluted sales and also created upset customers who thought they were buying real parts.

Resistor and caps.. It working for me.. I have test it on 12Vdc,24Vdc and 36Vdc.. But on single supply setting.. Can someone give the right diagram base on this 3 same chips? For dual and single supply…?

I test it on 24V 3A…it ok.. I already blow 2 TIP at same condition…The heat sink …super large lol.. T blow just like that after scnd.. I touch all the chip.. I still on normal load heat condition..

Single supply configuration. The sound wallaaa.. Sound super clean.. It keep silent..
