LM4731 Stereo 25W Audio Power Amplifier

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 fadein/out mute and a power conserving standby mode which can be controlled by external logic. The LM4731 has short circu.
