TDA7498 is 100W +100 W amplifier, using support monolithic integrated analog, logic and high pressure capabilities, 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%, to provide higher-quality listening experience. Main filter electrolytic capacitor with famous brand, capacity 2200UF, to ensure strong support for a steady stream of power. Use high-precision resistor 0805 chip resistors, the main circuit employs a precision of Â+/- 1% metal film resistors rings, ensure the machine a good signal to noise ratio. PCB using double-sided sheet 1.6mm thick, 2.0 oz copper thickness, HASL whole process to ensure that the size of the current through the good performance. PCB-class quality Specification: Work: Class D Quiescent Current: 50mA Efficiency: 90% Rated output power: 2 * 100W Frequency response: 20Hz to 20KHz Operating voltage: DC20V to DC36V Recommended supply voltage: DC32V Maximum output current: 7A PCB board size: 87 x72)mm Package Includes: 1 x Amplifier Board Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
