Description
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.
