MUSES72320
±18V Operation 2-Channel Electronic Volume
GENERAL DESCRIPTION
The MUSES72320 is a ±18V operation 2-channel
electronic volume, which is optimized for high-end audio
and professional audio applications with advanced circuitry
and layout. The MUSES72320 performs low noise and low
distortion characteristics and with resistance ladder circuit.
All of functions are controlled via three-wired serial bus.
Selectable 8-Chip address is available for using four chips
on same serial bus line.
It’s suitable for highly linear volume control of Hi-fi audio
systems.
