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 –∞.
