TDA7492 Digital Power Amplifier Board

50W*2

Product Introduction:

TDA7942 digital power amplifier board is based on TDA7492, with high cost performance!!! The price is not expensive, but the sound quality is very good, which can be said to be the bane of analog IC. LM3886 with hundreds of yuan may not have good sound quality! It is suitable for making multimedia, desktop power amplifiers, etc., multi-channel power amplifiers, playing electronic frequency division, manufacturing subwoofer power amplifiers, etc., with simple power supply (DC single voltage of 10-26V can be used), 24 V power supply of 4-ohm speakers can reach 50w+50w, maximum power of 50W * 2/8 Ω, single-channel BTL power of 100W/4 Ω, small size, about 70 * 57mm, height of 21mm (including heat sink), shipped with heat sink. Maximum frequency response: 20K

Features Are As Follows:

1. SMT high-speed chip mounter is used for chip placement. The performance of reflow soldering at high temperature is very stable. Non-manual welding process can be compared

2. It has four groups of gain adjustment (note that batch orders can provide technical support. If a single chip is used, don't ask how to change it. The gain of this board is adjusted to the maximum by default)

3. The ultra-small size of 70X57MM can be used to repair, polish the active speaker, improve the sound quality, or combine multiple pieces into multi-channel power amplifier or 2.1 power amplifier, which has many uses

4. It is equipped with super-strong output short circuit and over-temperature overload protection, and can prevent switching shock, which is rare in other 50W power amplifier boards.

Precautions For Use:

When the horn impedance is 4 Ω, the working voltage must be less than 18V, when the horn impedance is 6 Ω, the working voltage cannot exceed 24V, when the horn impedance is 8 Ω, the working voltage cannot exceed 26V, and the power polarity should not be reversed
