LC75397E
Overview
- 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 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.
