TDA7498 is 100W +100 W amplifier, using support monolithic integrated analog, logic and high pressure capabilities, reduce crosstalk and improve sound quality<br> The BCD6S high power output circuits are integrated complementary NMOS and PMOS istors, eliminating the old process required bootstrap capacitor and the cathode of the diode load. TDA7498 distortion ( + N) is less than 0.01%, to provide higher-quality listening experience.<br> electrolytic capacitor with famous , capacity 2200UF, to strong support for a steady stream of power.<br> Use high-precision resistor 0805 chip resistors, the main circuit employs a precision of Â+/- 1% metal film resistors rings, the machine a good signal to noise ratio.<br> PCB using double-sided sheet 1.6mm thick, 2.0 oz copper thickness, HASL whole process to that the size of the current through the good performance.
