1 / 17 page Ordering number : ENN*7378 D1503TN (OT) No. 7378 -1/17 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.
