PRODUCT OVERVIEW

The Parallel-Port AD1848K SoundPort? Stereo Codec integrates the key audio data conversion and control functions into a single integrated circuit. The AD1848K is intended to provide a complete, single-chip audio solution for business audio and multimedia applications requiring operation from a single +5 V supply. It 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 AD1848K generates enable and direction controls for IC buffers such as 74_245.
