The TDA7498 is the first amplifier on the market with a power rating of 100W+100W. It is an advanced sixth-generation BCD6S process (bipolar/CMOS/DMOS) that supports monolithic integrated analog, logic and high voltage functions. Compared to other Class D amplifiers, ST's BCD6S process achieves a higher chip area energy efficiency ratio while reducing crosstalk and improving sound quality. In addition, the BCD6S allows the integration of NMOS and PMOS complementary transistors in high power output circuits, eliminating the need for external bootstrap capacitors and cathode load diodes for legacy processes. This method simplifies design, saves board space, improves product design reliability, and optimizes material costs. Features: 1. Adopt original TDA7498. 2. The electrolytic capacitor adopts imported 2200UF/35V electrolysis to ensure strong and continuous power support. 3. The resistor uses 1206 0805 high-precision chip resistor to ensure a good signal-to-noise ratio of the whole machine. 4. PCB adopts 1.6mm thick double-sided sheet, 2.0 oz copper thickness, and tin-spraying process to ensure good passing performance of large and small currents. First-class PCB quality. 5. With fully enclosed dust-proof potentiometer, the performance is more stable and more durable than ordinary potentiometers. 6. Power and sound are beyond TA2024 TDA7492. 7. The volume is very small and the power is large.
