The LM4731 is a stereo audio amplifier capable of delivering typically 25W per channel of continuous average output power into a 4Ω or 8Ω load with less than 10% THD+N from 20Hz - 20kHz.
Each amplifier has an independent smooth transition fade in/out mute and a power conserving standby mode which can be controlled by external logic.
The LM4731 has short circuit protection and a thermal shutdown feature that is activated when the die temperature exceeds 150˚C. The LM4731 also has a under voltage lockout feature for click and pop free power off and on.
The LM4731 has a wide operating supply range from +/-10V - +/-28V allowing for lower cost unregulated power supplies to be used.
