LV1116N/NV Surround Processor ICs for

Electronic Volume Control

Overview

The LV1116N/NV are sound processor ICs developed for use in TV sets.

They incorporate the surround processing functions including (AViSS), pseudo stereo function, (L+R) output, and

the major functional blocks of an electronic volume control IC.

Functions

• Input function SWs (stereo inputs [L, R]).

• LINE OUT pin (through output).

• Input gain control (-6dB, -4dB, 0dB, 4dB, 6dB: 5 positions).

• AViSS (ON/OFF/4-stage level control).

• Tone control (BASS: ±20dB, TREBLE: ±18dB [in 2dB steps]).

• Master volume control (0dB~-14dB: 1dB steps/-14dB~-80dB: 2dB steps/-∞=-82dB).

• Balance control.

• THROUGH mode/MUTE mode.

• Pseudo stereo function (ON/OFF/MONO).

• L+R output with LPF (MUTE + 7-stage level control: 8 positions).

• I2C bus control.

* Initial output gain of L+R can be controlled by the resistance value of external resistor.
