TDA7498 is first 100W+100W amplifier in the currently market, adopted the integrated simulation, logic and high voltage function, and the other class D amplification process to create more chip area is compared, meaning law semiconductor BCD6S efficiency ratio, at the same time it can reduce the crosstalk, improve the quality. In addition, the BCD6S integration of NMOS and PMO is high power output circuit that is currently available in the market first 100W+100W complementary S transistor amplifier, the bootstrap capacitor and bootstrap diode eliminates the old process required. THD+N of ST TDA7498 is less than 0.01%, can provide more high-quality listening experience.
