This stereo audio amplifier board with MAX9736A can produce 15 watts into 8Ω loads. It operates from 8V to 28V and provides high PSRR, eliminating the need for a regulated power supply. The high performance MAX9736A 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 0.01W when in stand-by). Its reliability and longevity is ensured by a variety of protection including over/under voltage protection, over current protection and over temperature protection.
