LC75397E Datasheet | SANYO

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 1d B step between 0 d B and - 79 d B and - ∞. This circuit can control a total of 5 independent channels. - Equalizer: The chip provides control in 2-d B steps over the range between +10 d B and - 10 d B. 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 d B in 2d B steps. - Bass control: The bass can be controlled over a ±10 d B range in 2-d B steps.
