The NE5241 is a complete stereo digital to audio converter for the Dolby ADM digital audio system, which allows CD quality stereo audio to be delivered with data rates on the order of 400 to 600kb/s. The NE5241 is intended for use in high quality consumer digital audio equipment for the reproduction of broadcast (or pre-recorded) digital audio.
The NE5241 is a bipolar implemented integrated circuit designed as a complete stereo digital-to-audio converter for the Dolby ADM digital audio system. It enables CD quality stereo audio delivery with data rates between 400 and 600kb/s, intended for high-quality consumer equipment reproducing broadcast or pre-recorded digital audio.
The device incorporates channel de-multiplexing, data input latches, control signal filter drivers, buffers, variable gain integrators, and variable de-emphasis filters. It features precision temperature-compensated voltage reference circuitry to ensure accurate performance over temperature variations.
