Surround Processor Integrated Circuit ICs for Electronic Volume Control LV1116N

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.
