Product Summary
The AD1848KP-REEL is a Parallel-Port 16-Bit SoundPort Stereo Codec. It integrates the key audio data conversion and control functions into a single integrated circuit. The AD1848KP-REEL is intended to provide a complete, single-chip audio solution for business audio and multimedia applications requiring operation from a single +5V supply. The AD1848KP-REEL provides a direct, byte-wide interface to both ISA (“AT”) and EISA computer buses for simplified implementation on a computer motherboard or add-in card. The AD1848KP-REEL generates enable and direction controls for IC buffers such as 74_245.
