Overview:
Welcome to use this 1 x 600W Class-D audio amplifier board series by Sure Electronics.
It integrates TI’s high performance TAS5630 supporting single channel audio amplification.
Single channel is capable of outputting nominal power simultaneously and continuously. It’s
subtable for amplifier enthusiasts or hobbyists to finish a complete amplifier system. Resistance
and capacity components of high quality, including X7R ceramic capacitors, Metallized Polyester
(PET) Capacitors and lower ESR electrolytic capacitors, high performance inductors are used to
gain the perfect timber, finally realize high S/N ratio, low THD+N, wide frequency response range etc
Arobust heatsink, two-stage cooling fan, as well as protection circuits to protect againstover/under
voltage, over current, short circuit, and over temperature conditions are built-in for years of
enjoyment. Four fixed gain settings allow you to match the amplifier to your source, and use your
source as the volume control. A 25 to 50 VDC power supply is required.
