Product Summary

The AD1849KP is a Serial-Port 16-Bit SoundPort Stereo Codec integrates the key audio data conversion and control functions into a single integrated circuit. The AD1849KP is intended to provide a complete, single-chip audio solution for multimedia applications requiring operation from a single +5 V supply. External signal path circuit requirements are limited to three low tolerance capacitors for line level applications; anti-imaging filters are incorporated on-chip. The AD1849KP includes on-chip monaural speaker and stereo headphone drive circuits that require no additional external components.
