4 x 100Watt Class D Audio Amplifier Board – TDA7498

Manual: AA-AB33184

Warranty

Overview：

Welcome to use this self-made 4 x 100W audio amplifier board which has perfect class-D architecture and integrated TDA7498 chip to achieve the 100W per channel power output.

With high efficiency, it especially is available for the outdoor venues where power supply is always in

consideration. Resistance and capacity components of high quality, including X7R ceramic capacitors

and lower ESR electrolytic capacitors, are used to gain the perfect timber, finally realize high S/Nratio,

low THD+N, wide frequency response range etc.
