Single-Chip Electronic Volume Control System
LC75395E
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
