CMOS IC
LC75343M
Electronic Volume Control System on-Chip
Overview
The LC75343M is an electronic volume system that can
control the volume, balance, 2-band equalizer, super bass,
and input switching functions by serial data input.
Note*: Regarding (Bass) and (Super bass) above, MID
and BASS functions can also be realized by
changing the capacitor capacitance.
Features
鈥?On-chip buffer amplifier cuts down number of external
components
鈥?Low switching noise generated by on-chip switch due to
use of silicon gate CMOS process
鈥?On-chip reference voltage circuit for analog ground
鈥?Controls performed with serial data input (CCB)
Functions
鈥?Volume: 0 dB to 鈥?8 dB (1-dB step) and 鈥撯垶 (64
positions)
0 dB to 鈥?0 dB (1-dB step), 鈥?0 dB to 鈥?0 dB
(2-dB step), 鈥?0-dB to 鈥?8 dB (4-dB step)
Balance function with separate L/R control
鈥?Treble: 鹵10-dB control in 2-dB steps is possible.
Shelving characteristic.
鈥?Bass*: 鹵10-dB control in 2-dB steps is possible. Peaking
characteristics.
鈥?Super bass*: +10-dB control in 2-dB steps is possible.
Peaking characteristics.
(+/鈥?0 dB control in 2-dB steps is possible
depending on software support and the
application. Peaking characteristics.)
鈥?Selector: 5 input signals can be selected both for
L and R
鈥?Input gain: 0 dB to +30 dB (2-dB step) amplification is
possible for the input signal.
鈥?General-purpose amp (ATT): 2 on-chip general-purpose
amplifiers
(0-dB to 鈥?8-dB in 2-dB
steps and 鈥撯垶 11 positions
attenuate control is
possible, depending on
software support and the
application)
