Overview

Ordering number : EN6108 CMOS IC LC75397E Single Chip Electronic Volume and Tone Control System Overview The LC75397 is an electronic volume control system providing control over volume, balance, 4-band equalizer, bass, and input switching based on serial inputs.
Features • Built-in buffer amplifiers reduce the number of external parts required.
• Silicon gate CMOS process reduces the noise of built-in switch.
• Built-in analog ground reference voltage generator circuit • All functions are controlled by serial input data.
This IC supports the CCB standard.
Functions • Volume control: The chip provides 81 levels of volume attenuation: in 1dB step between 0 dB and –79 dB and –∞.
This circuit can control a total of 5 independent channels.
• Equalizer: The chip provides control in 2-dB steps over the range between +10 dB and –10 dB.
Three of the four bands have peaking equalization; the remaining one, shelving equalization.
• Selector: The left and right channels each offer a choice o...
