Single-Chip Electronic Volume Control System

N3095HA (OT) No. 5201-1/13

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

• Input and output signal switching: The four I/O switches

can be set to on or off independently.

• Volume control: Independent control of the left and

right channels can be used to implement a balance

function.

0 to –20 dB in 2 dB steps, –20 to –32 dB in 3 dB steps,

–32 to –53 dB in 4 dB steps, –52 to –70 dB in 4.5 dB

steps, and –

∞.

• Tone controls: Four frequency characteristic types

selectable by setting internal switches.

Also supports a buffer function that requires no external

components.

• Two general-purpose output ports: These ports allow

this LSI to control motorized volume controls and

general-purpose logic.
