LC75395E
Single-Chip Electronic Volume Control System
Overview
The LC75395E is an electronic volume control that
provides volume, balance, five-band equalization and
input switching functions. These functions are controlled
from serial input data.

Functions
• Volume control: The volume control provides 25
attenuation positions: from 0 dB to –17.5 dB in 1.25 dB
steps, from –17.5 dB to –25 dB in 2.5 dB steps, from
–25 dB to –36.25 dB in 3.75 dB steps and with settings
for –41.25 dB, –50 dB, –60 dB and –∞.
A balance function can be implemented by controlling
the left and right channels independently.
• Equalizer: The equalizer function supports ±10 dB
control in 2 dB steps in each of the five bands. Of the
five bands, four provide peaking characteristics, and one
provides shelving characteristics.
• Selector: The selector function selects one of four inputs
for each of the left and right channels. An arbitrary
amplification level can be set for each input signal using
external components.
• Serial data input: All controls can be set from serial
input data (CCB format)
Features
• On-chip buffer amplifiers to minimize the number of
external components
• Silicon-gate CMOS process for minimal switching noise
• On-chip circuit to generate the V_DD/2 reference voltage
• CCB is a trademark of SANYO ELECTRIC CO., LTD.
• CCB is SANYO’s original bus format and all the bus
addresses are controlled by SANYO.
