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.
Functions
Volume: 0 to –95 dB (in 1 dB 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 dB range in 2 dB 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 zero-
cross detection and dedicated pins.
External output ports: Provides 4 n-channel transistor
open-drain outputs.
Features
Built-in buffer amplifiers reduce the number of external
components to a minimum.
Fabricated in a silicon-gate CMOS process for minimal
noise generation from internal switches.
Built-in analog ground reference voltage generator
circuit
All settings are controlled by serial data transmitted over
a CCB interface.
