DESCRIPTION
The UTC It is featured in unity-gain stability. The shutdown mode is externally controlled, active-high and micropower consumption. An internal thermal shutdown protection circuit is contained in the device. Operating on a 5V power supply, it can drive 16Ω load at 105mW per channel of continuous average power with 0.1% (THD+N). This device is mainly used to provide customers with higher quality output power but less required external components. The UTC LM4811 reduces the use of bootstrap capacitors or snubber networks that make making it ideal for low-power portable systems applications. The UTC LM4811 is generally applied in cellular phones, MP3, CD, DVD players, PDA’s and other portable electronics.●
