LC75410E Overview
ENN7027 CMOS IC LC75410E, 75410W Electronic Volume Controller for Car Audio Systems Overview The LC75410E and 75410W are electronic volume controllers that enable control of volume, balance, fader, bass/treble/mid, loudness, input switching, and input gain using only a small number of external ponents.
LC75410E Key Features
- On-chip buffer amplifier cuts down number of external ponents
- Low switching noise generated by on-chip switch through use of silicon gate CMOS process, for low switching noise when t
- 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)
- Volume: 0 dB to -79.5 dB in 0.5-dB steps, and -∞ (161 positions) Balance function with separate L/R control
- Bass/treble/mid: Each band 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: five input signals can be selected for Left and for Right (Four are singleended inputs and one is a dif
- Loudness: A tap is output from the -32 dB position of a 2 dB step volume control resistor ladder. A loudness function ca
