LV1116NV

Ordering number : ENN8262 Bi-CMOS LSI LV1116N/NV 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.
