TDA7498 is 100W +100 W amplifier, using support monolithic integrated analog, and high pressure capabilities, reduce crosstalk and sound quality The BCD6S output circuits are integrated complementary NMOS and PMOS transistors, eliminating the process required bootstrap capacitor and the cathode of the diode load. STMicroelectronics TDA7498 distortion ( + N) is less than 0.01%, to higher-quality experience. electrolytic capacitor with famous brand, capacity 2200UF, to strong support for a steady of power. Use high-precision resistor 0805 chip resistors, the main circuit employs a precision of +/- 1% metal film resistors rings, the machine a good signal to noise . PCB using double-sided sheet 1.6mm thick, 2.0 copper thickness, HASL whole process to 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 and different displays may cause the color of the item in the a little different from the real . The measurement allowed is +/- 1-3cm.
