LV1116N-E Surround Processor IC Electronic Volume Control for TV Audio Systems
The LV1116N-E is a sound processor IC designed for TV sets, integrating surround processing, pseudo stereo, and electronic volume control. Features include input gain control, tone control with ±20dB bass and ±18dB treble, volume control down to -82dB, and I2C bus control. Ideal for efficient audio management.
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.
Features
• 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]).
• Volume control
(0dB to −14dB: 1dB steps/−14dB to −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).
• I2 C bus control. * Initial gain of L+R AMP can be controlled by the resistance value of external resistor.
