The TDA7498 is the first 100W+100W amplifier on the market. It supports monolithic integrated analog, logic and high voltage functions to provide you with a fine quality listening experience.
TDA7498 is the first 100W+100W amplifier on the market. It supports monolithic integrated analog, logic and high voltage functions. It also can reduce crosstalk and improve sound quality.
The BCD6S high power output circuits are integrated complementary NMOS and PMOS transistors, eliminating the old process required bootstrap capacitor and the cathode of the diode load. STMicroelectronics TDA7498 distortion (THD+N) is less than 0.01%, which provides fine quality listening experience.
Using TDA7498, has a long service life.
The main filter electrolytic capacitor adopts famous brand and the capacity is 2200UF, which guarantees strong and continuous power support.
Use high-precision resistor 0805 chip resistors, the main circuit employs a precision of ± 1% metal film resistors rings, ensuring the machine has a good signal to noise ratio.
PCB uses 1.6mm thick double-sided sheet, 2.0 ounce copper thickness, spray tin full process, ensuring good passing performance of large and small current.
