NE5241 Datasheet, PDF (1/6 Pages) NXP Semiconductors – Dolby ADM digital audio decoder

Philips Semiconductors
Dolby ADM digital audio decoder
Product specification
NE5241
DESCRIPTION
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 IC contains channel de-multiplexing data input
latches, control signal filter drivers and buffers, variable gain
integrators, and variable de-emphasis filters. Precision, temperature
compensated voltage reference circuitry assures accurate
performance over temperature. The IC is implemented in a bipolar
process to achieve low noise, low distortion, and wide dynamic
range. The NE5241 is an improved version of the NE5240, which
has been discontinued.
Note:
The NE5241 is available only to licensees of Dolby Laboratories Licensing Corporation,
from who licensing and applications information must be obtained. Dolby is a registered
trademark of Dolby Laboratories Licensing Corporation, San Francisco, California.
