UNISONIC TECHNOLOGIES CO., LTD S486 CMOS IC DUAL 100mW AUDIO POWER AMPLIFIER WITH STANDBY MODE DESCRIPTION The UTC S486 is a dual power amplifier capable of delivering typically 100mW per channel of continuous average power to an 8Ω load with 0.1% THD+N using a 5V power supply. The UTC S486 features an externally controlled, low-power consumption stand by mode. The UTC S486 exhibit a low quiescent current of typically 1.8mA, allowing usage in portable applications. The unity-gain stable UTC S486 can be configured by external gain-setting resistors.

Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied. 2. All voltage values are measured with respect to the ground pin. 3. Attention must be paid to continuous power dissipation (VDD x 300mA). Exposure of the IC to a short circuit for an extended time period is dramatically reducing product life expectancy.
