LC75347E
LC75347E is 6-Channel Single-Chip Electronic Volume Control System manufactured by SANYO.
Overview
The LC75347E is a 6-channel 97-step electronic volume control system IC that provides a 2-channel input selector, bass and treble tone controls, external output ports, and a zero-cross volume switching function.
- Built-in analog ground reference voltage generator circuit
- All settings are controlled by serial data transmitted over a CCB interface.

Functions
- Volume: 0 to
- 95 d B (in 1 d B steps) and
- ∞, for a total of 97 positions. Each of the six input channels can be controlled independently.
- Bass and treble: Each band can be controlled over a ±12 d B range in 2 d B steps. The bass control provides peaking characteristics and the treble control provides shelving characteristics.
- Selector: 2-channel input selector
- Zero cross: Provides independent zero-cross detection for each of the 6 channels and a timer overflow detection circuit.
- External muting: Mute in/mute out function using zerocross detection and dedicated pins.
- External output ports: Provides 4 n-channel transistor open-drain outputs.
