Sanyo LC75397E Specifications

Ordering number : EN6108
40799RM (OT) No. 6108-1/26
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.
Functions
• 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 of six inputs. The L6 and R6 inputs can be turned on and off independently. An external constant determines the amplification for the input signal.
• Input gain: The input signal can be amplified by 0 to +30 dB in 2­dB steps.
• Bass control: The bass can be controlled over a ±10 dB range in 2-dB steps.
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.
