Description
TDA7498 is currently the first 100W+100W amplifier on the market. It adopts support for monolithic integration of analog, logic and high-voltage functions. Compared with other Class-D amplification processes to create a higher chip area energy device, STMicroelectronics BCD6S has an efficiency ratio , While also reducing crosstalk and improving sound quality. In addition, the BCD6S high-power output circuit integrates NMOS and PMOS complementary transistors, eliminating the need for bootstrap capacitors and cathode load diodes required by the old process. The distortion degree (THD+N) of STMicroelectronics TDA7498 is less than 0.01%, which can provide higher quality listening experience.
Features
Using original TDA7498
The main filter electrolytic capacitor adopts a famous brand with a capacity of 2200UF, which ensures strong and continuous power support.
The resistance uses high-precision 0805 chip resistors, and the main circuit uses five-ring metal film resistors with an accuracy of ÷1%, which ensures a good signal-to-noise ratio of the whole machine.
PCB adopts 1.6mm thick double-sided board, 2.0 oz copper thickness, and full tin spraying process to ensure good passing performance of large and small currents. First-class PCB quality.
