Brief Introduction:
The MAX9736A Class D amplifiers provide high-performance, thermally efficient amplifier solutions.MAX9736A delivers 2 x 15W into 8Ω loads. This device operates from 8V to 28V and provides a high PSRR, eliminating the need for a regulated power supply. The MAX9736 offers up to 88% efficiency at 12V supply.
Comprehensive click-and-pop reduction circuitry minimizes noise coming into and out of shutdown or mute.
Features:
L-style Aluminium:
To improving the connection and measurement efficiency and saving the cost on installations, Sure Electronics provides a L-type aluminium bracket for audio amplifier boards. The aluminium bracket supports vertical and horizontal installtion ways to satisfy different installation requirements. With 4 M3 screw lock standoffs and 2 M3 pre-drilled mounting holes, audio amplifier boards could be installed on the bracket easily.

Safety Precautions:
1. In order to achieve a better sound quality, please use stable power supply since a bad or unstable
power supply may worsen the sound quality or even cripple the amplifier board.
2. Avoid metal objects
Protect this product well and move away metal objects from this product.
Warning:
Never immerse the product in the rain or any other humid environment to prevent the fire or electric shock.
