DESCRIPTION
The Digital Audio Range of transformers is
designed to improve the balance of
transmitter and receiver circuitry in hi-fi
equipment, video games and other
applications requiring high-performance
digital audio transmission. Compliant with
AES/EBU recommendations for the digital
audio interface offering optimised shunt
capacitance between primary and secondary
windings. Capable of operating over the
audio data rate frequency range, providing
isolation from 60Hz noise.
ABSOLUTE MAXIMUM RATINGS
Specifications typical at TA=25°C
For tape and reel packaging details refer to datasheet NDC AN002.
