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.
