Description

Being a family member of Low Power Stereo Series, this stereo amplifier board is capable of delivering 25W per channel into 8 Ohm load. The high performance TDA7492P is integrated to support dual channel audio amplification and achieve high efficiency. The module dissipates only 0.6W with no signal when in ON mode (around 0.1W when in stand-by mode). Excellent heat dissipation eliminates the requirement of an extra heatsink. Over temperature protection and over current protection increase its reliability.
