LC75384NE-R
Overview
- Volume: 81 positions: from 0 dB to -79 dB in 1-dB steps and -∞. A balance function can be implemented by controlling the left and right volume settings independently.
- Fader: Either the rear or front outputs can be attenuated over 16 positions. (16 positions: From 0 dB to -2 dB in 1-dB steps, from -2 dB to -20 dB in 2-dB steps, from -20 to -30 dB in one 10-dB step, -45 dB, -60 dB, and -∞.)
- Bass/treble/mid: Control over ±12 dB in 2-dB steps in each band.
- Input gain: The input signal can be amplified by from 0 dB to +18.75 dB in 1.25-dB steps.
- Input switching: The left and right channels can each be selected from one of 5 inputs. (Four are single-ended inputs and one is a differential input.)
- Loudness: Taps are output from a 2-dB step volume control ladder resistor starting at the -32-dB position. A loudness function can be implemented by attaching external capacitors and resistors.
- On-chip buffer amplifiers minimize the number of required external components.
- Minimal switching noise when no input signals are present due to fabrication in a silicon gate CMOS process that minimizes the noise generated by internal switches.
- Use of zero-cross switching circuits for internal switches minimizes switching noise when signals are present.
- Built-in VDD/2 reference voltage generator circuit
