TDA8954 420W + 420W 2.0 Class D digital power amplifier board
Product details:
TDA8954TH is the latest high-efficiency Class D high-power digital audio amplifier from Philips. The IC uses the HSOP24 power package, which has very low power consumption and quiescent current. Because it is a MOS tube output, it has a good performance in terms of sound quality. The bass is deep and powerful, and flexible.
1. Using original TDA8954TH
2. The main filter electrolytic capacitor uses a total capacity of 2200UF * 12
3. Two 25A rectifier flat bridges are used to ensure strong continuous power support.
4. The high-precision chip is selected for the resistance, which ensures the good signal-to-noise ratio of the whole machine.
5. PCB uses 1.6mm thick double-sided sheet, 2.0 oz copper thickness, full process of tin spraying, guaranteed size
Good current passing performance. Best-in-class PCB quality.
6. The output uses a red ring high current inductor to ensure that the sound is crisp and powerful.
7. When using BTL bridge, it can output 420W under 8 ohm load
