Surround Processor ICs for
Electronic Volume Control
LV1116N/NV
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).
I
2
C bus control.
* Initial output gain of L+R can be controlled by the resistance value of external resistor.
