Ordering number : ENN6928

CMOS IC

LC75411ES, 75411WS

Electronic Volume Controller

for Car Audio Systems

Overview

The LC75411ES and 75411WS are electronic volume controllers that enable control of volume, balance, fader, bass/treble, loudness, input switching, and input gain using only a small number of external components.

Functions

• Volume: 0 dB to –79.5 dB in 0.5-dB steps, and –∞ (161 positions) Balance function with separate L/R control

•Fader: rear output or front output can be attenuated across 16 positions (in 1-dB steps from 0 dB to –2 dB, 2-dB steps from –2 dB to 20 dB, 10-dB

steps from –20 dB to –30 dB, and –45 dB, –60 dB, –∞ )

•Bass/treble: Both bass and treble can be controlled in

1-dB steps from 0 dB to ±6 dB, and in 2-dB steps from ±8 dB to ±12 dB.

• Input gain: 0 dB to +18.75 dB (1.25-dB steps) amplification is possible for the input signal.

• Input switching: four input signals can be selected for Left and for Right

• Loudness: A tap is output from the –32 dB position of a 2 dB step volume control resistor ladder. A loudness function can be implemented by connecting an external RC circuit.

Features

•On-chip buffer amplifier cuts down number of external components

•Low switching noise generated by on-chip switch through use of silicon gate CMOS process, for low switching noise when there is no signal

•Low switching noise when there is a signal due to use of on-chip zero-cross switching circuit

•On-chip 1/2 VDD reference voltage circuit

•Controls performed with serial input (CCB)

•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.

Any and all SANYO products described or contained herein do not have specifications that can handle applications that require extremely high levels of reliability, such as life-support systems, aircraft’s control systems, or other applications whose failure can be reasonably expected to result in serious physical and/or material damage. Consult with your SANYO representative nearest you before using any SANYO products described or contained herein in such applications.

SANYO assumes no responsibility for equipment failures that result from using products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other parameters) listed in products specifications of any and all SANYO products described or contained herein.
