TDA7498 SubWoofer Amplifier Board [150W]
TDA7498 amounts is the market's first power amplifier supports single chip integrated analog, logic and advanced sixth-generation BCD6S processes of high pressure functions (double/CMOS/DMOS). Compared with other class-d amplifiers, ST BCD6S process to achieve higher chip area efficiency, while mitigating crosstalk and improves sound quality. In addition, the BCD6S allow high power output complement integrated NMOS and PMOS transistors in the circuit, eliminating the old process required for external bootstrap capacitors and cathode diode load. This approach simplifies the design of the system, saving board space and improves the reliability of product design, and optimize the cost of materials.
n The original TDA7498
n Electrolytic Capacitor uses the import 2200UF/35V electrolysis to ensure strong continuous support.
n High resistance using 1206 0805 precision chip resistors, to ensure good signal to noise ratio of the whole machine.
n Totally enclosed dust potentiometer, the performance is more stable and more durable than ordinary potentiometer.
