Ordering number : ENN692862901RM (OT) No. 6928-1/34OverviewThe LC75411ES and 75411WS are electronic volumecontrollers that enable control of volume, balance, fader,bass/treble, loudness, input switching, and input gainusing only a small number of external components.Functions• Volume: 0 dB to –79.5 dB in 0.5-dB steps, and –∞ (161positions) Balance function with separate L/Rcontrol• Fader: rear output or front output can be attenuatedacross 16 positions (in 1-dB steps from 0 dB to–2 dB, 2-dB steps from –2 dB to 20 dB, 10-dBsteps from –20 dB to –30 dB, and –45 dB,–60 dB, –∞)• Bass/treble: Both bass and treble can be controlled in1-dB steps from 0 dB to ±6 dB, and in 2-dBsteps 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 forLeft and for Right• Loudness: A tap is output from the –32 dB position of a2 dB step volume control resistor ladder.A loudness function can be implemented byconnecting an external RC circuit.Features• On-chip buffer amplifier cuts down number of externalcomponents• Low switching noise generated by on-chip switchthrough use of silicon gate CMOS process, for lowswitching noise when there is no signal• Low switching noise when there is a signal due to useof on-chip zero-cross switching circuit• On-chip 1/2 VDD reference voltage circuit• Controls performed with serial input (CCB)LC75411ES, 75411WSSANYO Electric Co.,Ltd.
