Features

* a 32-step digital volume control and eight distinct output modes. The digital volume control, 3D enhancement, and output modes are programmed through a two-wire I2C compatible interface that allows flexibility in routing and mixing audio channels. The RF suppression circuitry in the LM4947 makes it

Applications

* in which strong RF signals generated by an antenna (and long output traces) may couple audibly into the amplifier. The LM4947 is designed for cellular phones, PDAs, and other portable handheld applications. It delivers high quality output power from a surface-mount package and requires only eight ex
