TDA8954 420W + 420W 2.0 Class D Digital Power Amplifier Board (Fan Cooling)
All parts of this product are original authentic, unpretentious, pure quality;
the use of high-quality original parts, not only the safety and quality are guaranteed,
long service life, more important is to ensure that the actual performance can
achieve the design goals. The pursuit of quality is the consistent aim of the store.
The TDA8954TH is Philips' latest high-efficiency Class D high-power digital
audio amplifier. The IC is available in a HSOP24 power package with low power
consumption and quiescent current. Since the internal is the MOS tube output,
it has a good performance in terms of sound quality. The bass is deep and
powerful, and its elasticity is good.
n using original TDA8954TH
n The main filter electrolytic capacitor uses a total capacity of 2200UF*12
n Two 25A rectified flat bridges are used to ensure a strong and
continuous power support.
n Resistor selects high precision patch to ensure good signal to
noise ratio of the whole machine.
n PCB with 1.6mm thick double-sided sheet, 2.0 oz copper thickness,
spray tin full process, to ensure the size
Good pass performance of current. First-class PCB quality.
The output uses red ring high current inductor to ensure the sound is crisp and powerful.
n When using BTL bridge, it can output 420W under 8 ohm load
