TDA7492 Stereo High Amplifier Board 2x50W Class D

TDA7492 Stereo High Amplifier Board 2x50W Class D

TDA7942 digital power amplifier board is based on STMicroelectronics' TDA7492, which is cost-effective! ! ! The price is not expensive, but the sound quality is very good, it can be said to be the analog IC's nemesis. A few hundred yuan of LM3886 may not have this sound quality! Suitable for multimedia, desktop power amplifier, etc., suitable for multi-channel power amplifier, playing electronic crossover, manufacturing subwoofer power amplifier, etc., power supply is simple (DC single voltage 10-26V can be), 4 Euro speaker 24v power supply can reach 50w

+50w, Maximum power 50W*2/8 ohms, mono BTL power 100W/4 ohms, small size, about 70*57mm, height 21mm (including heat sink) with heat sink when shipped.

The highest frequency response: 20K


features are as follows:

1, using SMT high-speed placement machine patch, over-temperature reflow soldering, performance is very stable, non-manual welding process can be compared

2, with 4 sets of gain adjustment (remarks bulk orders can provide technical support If you are a single piece, don't ask how to change it. The gain of this board is adjusted to the maximum by default.

3. The ultra-small 70X57MM can be used to repair, polish the active speakers, improve the sound quality, or combine multiple blocks into a multi-channel amplifier or 2.1 power amplifier, the use of a lot of

4, comes with a strong output short circuit and over temperature overload protection, and prevent the switch machine impact, which is rare in other 50W power amplifier board

Note:
      When the speaker impedance is 4 ohms The working voltage must be less than 18V, the horn impedance is 6 ohms, the working voltage can't exceed 24V, the horn impedance is 8 ohms, the working voltage can't exceed 26V, and the power polarity should not be reversed.
