KA8602-HLF Low Voltage Audio Power Amplifier IC | SOP-8 Differential Output

The KA8602-HLF is a compact, low-voltage audio power amplifier IC designed for portable audio devices, small speaker systems, and embedded sound applications. Featuring differential outputs, the KA8602 maximizes output swing even at low supply voltages—ideal for battery-powered audio circuits.

This IC eliminates the need for output coupling capacitors, reducing component count and PCB space. Its gain can be easily adjusted using only two external resistors. With low distortion, low quiescent current, and a built-in mute function, the KA8602-HLF provides clean and efficient audio amplification in a small SOP-8 package.
