CMOS LSI
LC75391, 75391M
Single-Chip Electronic Volume Control System
Overview
The LC75391 and LC75391M are single-chip electronic
volume and tone control systems that support volume
control, tone control, and input and output signal
switching functions controlled by serial input data.

Functions
鈥?Input and output signal switching: The four I/O switches
can be set to on or off independently.
鈥?Volume control: Independent control of the left and
right channels can be used to implement a balance
function.
0 to 鈥?0 dB in 2 dB steps, 鈥?0 to 鈥?2 dB in 3 dB steps,
鈥?2 to 鈥?3 dB in 4 dB steps, 鈥?2 to 鈥?0 dB in 4.5 dB
steps, and 鈥撯垶.
鈥?Tone controls: Four frequency characteristic types
selectable by setting internal switches.
Also supports a buffer function that requires no external
components.
鈥?Two general-purpose output ports: These ports allow
this LSI to control motorized volume controls and
general-purpose logic.
