1.1 Overview
Welcome to use this self-made 6*100W audio amplifier board which is a perfect class-D
architecture integrated TDA7498 chip to achieve the single-channel 100W 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/N ratio, low THD+N, wide frequency response range etc.
Briefly, the power supply range and heat sink performance of each product distinguishes.
You may make the proper choice to meet your application needs.
