Manufacturer Part Number
lc75412e
Description
Electronic Volume Controller For Car Audio Systems
Manufacturer
Sanyo Semiconductor Corporation
Datasheet
Ordering number : ENN7053
Overview
The LC75412E and 75412W 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 dB in 1-dB steps, and –∞ (81
• Fader: rear output or front output can be attenuated
• Bass/treble: Each band can be controlled in 2-dB steps
• Input gain: 0 dB to +18.75 dB (1.25-dB steps)
• Input switching: Six input signals can be selected for
• Loudness: A tap is output from the –32 dB position of a
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, –∞)
