TDA7498 Class D Subwoofer Amplifier 100W Bass Digital Power Amplifier Board

Description:

Features an advanced sixth generation BCD6S process (bipolar / CMOS / DMOS) that monolithic integrated analog, logic and high voltage capability.
Compared with other Class D amplifiers, ST's BCD6S process achieves higher chip area energy efficiency, crosstalk reduction and improved sound quality.
In addition, the BCD6S allows NMOS and PMOS complementary transistors to be integrated into high-power output circuits.
The electrolytic capacitor adopts imported 2200UF / 35V electrolysis, and the resistor uses 1206 0805 high-precision chip resistor to ensure a good signal-to-noise ratio of the whole machine.
With a fully enclosed dust-proof potentiometer, the performance is more stable and more durable than ordinary potentiometers. Both power and sound exceed TA2024 TDA7492.
PCB board adopts 1.6mm thick double-sided sheet, 2.0 oz copper thickness, and the whole process of tin-spraying ensures the good passing performance of the current. First-class PCB quality.
