natlinear LN4812
LN4812 is a differential input stereo audio power amplifier circuit for mobile phones and other portable audio devices built-in speaker. It provides a stable output power of 150mW 16Ω loads. The shutdown current of the LN4812 is less than 100nA, that can save energy for the system.GENERAL DESCRIPTION
At the same time the amplifier gain can be set by external resistors, that it is easy to use. The LN4812 using small MSOP-10 package, to facilitate high-density mounting .●
