LC75345M
Electronic Volume Control System
on-Chip
Overview
The LC75345M is an electronic volume system that can
control the volume, balance, 2-band equalizer, super bass,
and input switching functions by serial data input.
Functions
• Volume: 0 dB to –78 dB (1-dB step) and –(64
positions)
0 dB to –50 dB (1-dB step), –50 dB to –70 dB
(2-dB step), –70-dB to –78 dB (4-dB step)
Balance function with separate L/R control
• Treble: ±10-dB control in 2-dB steps is possible.
Shelving characteristic.
• Bass: ±10-dB control in 2-dB steps is possible. Peaking
characteristics.
• Super bass: +10-dB control in 2-dB steps is possible.
Peaking characteristics.
• Selector: 5 input signals can be selected both for L and
R
• Input gain: 0 dB to +30 dB (2-dB step) amplification is
possible for the input signal.
• General-purpose amp (ATT): 2 on-chip general-purpose
amplifiers
Features
• On-chip buffer amplifier cuts down number of external
components
• Low switching noise generated by on-chip switch due to
use of silicon gate CMOS process
• On-chip reference voltage circuit for analog ground
• Controls performed with serial data input (CCB)
