LC75372E Overview
EN5330 CMOS LSI LC75372E Electronic Volume Control for Car Stereo Systems Overview The LC75372E is an electronic volume control that can implement volume, balance, fader, bass/treble, loudness, input switching, and input level control functions with a minimal number of external ponents. Built-in reference voltage generation circuit Serial data input: Supports CCB format munication with the system controller.
LC75372E Key Features
- Volume: Provides 81 positions, from 0 dB to -79 dB (in 1-dB steps) and
- Bass/treble: Forms an NF-type tone control circuit (LUX type) with the addition of external capacitors. The base and tre
- Loudness: The volume resistor ladders are tapped starting at the -20-dB position. A loudness function can be implemented
- The signal can be selected from one of three inputs for each of the left and right channels. The input signals can be am
- On-chip buffer amplifiers for a minimum of external ponents
- Minimal switching noise due to fabrication in a silicongate CMOS process
