Description
The MAX9768BETG+T is a high-efficiency, Class D audio power amplifier designed for various audio applications. It features an integrated charge-pump inverter, allowing it to deliver up to 10 watts of continuous output power to a single 8-ohm load from a single 5V supply. This device operates with high efficiency, reducing the need for large heat sinks and minimizing power consumption. The integrated charge pump provides a negative supply voltage, eliminating the need for DC-blocking capacitors on the output, which simplifies design and reduces component count.
Key features include low distortion and noise, an output protection circuit, and thermal overload protection. The MAX9768BETG+T also offers high PSRR (power supply rejection ratio), making it robust against supply noise and fluctuations. It is packaged in a thermally enhanced 24-pin TQFN, making it suitable for compact applications. This amplifier is ideal for use in portable audio devices, television sets, and other consumer electronics where efficient amplification and minimal space are critical.
