LC75397E Overview
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.
LC75397E Key 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
- Volume control: The chip provides 81 levels of volume attenuation: in 1dB step between 0 dB and -79 dB and -∞. This circ
- Equalizer: The chip provides control in 2-dB steps over the range between +10 dB and -10 dB. Three of the four bands hav
