- Model Number:19J044
- Type:Amplifier IC Development Boards and Kits
- Place of Origin:China
TDA7492 TDA7492 digital amplifier plate board is the core, cost-effective! ! The price is not expensive, but the sound quality is very good, it can be said is the nemesis of the analog IC. Several hundred dollars LM3886 may not have this sound good! Suitable for multimedia, desktop amplifier, multi-channel amplifier, playing electronic crossover, manufacture subwoofer amplifier, etc., simple power supply (10-26V DC single voltage can be), the maximum power of 50W * 2/8 Europe, mono BTL power 100W / 4 in Europe, small size, 70 * 57mm, height 21mm (including fins) finned shipped. Switch machine impact sound is very small, almost negligible.
Features
1, using high-speed SMT placement machine, over temperature reflow, performance is very stable, non-manual welding process can be compared
2, with four groups gain adjustment (Note bulk orders can provide technical support, single-chip, then do not ask how changed the default gain adjustment plate to the maximum)
3, ultra-small size 70X57MM can be used to repair, polish speakers, improving the sound quality, can also be combined into multi-block or multi-channel amplifier 2.1 amplifier, use a lot of
4, comes with super output overload short-circuit and over-temperature, shock and prevent the switching machine, which is rare in other 50W amplifier plate
5, the highest frequency response: 20K
Caution
Note: When the speaker impedance is 4 ohms, the operating voltage must be less than 18V, speaker impedance is 6 euro, the operating voltage can not exceed 24V, speaker impedance is 8 ohms, the working voltage can not exceed 26V, do not reverse polarity power supply.
