Sanyo LC75411WS Specifications

Ordering number : ENN6928

62901RM (OT) No. 6928-1/34

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)
