Overview
Surround Processor ICs for Electronic Volume Control
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/-•‡ • 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.
=-82dB).
* Initial output gain of L+R can be controlled by the resistance value of external resistor.
