Ordering number : ENN8262 Bi-CMOS LSI LV1116N/NV Surround Processor ICs for Electronic Volume Control 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). • I2C bus control. * Initial output gain of L+R can be controlled by the resistance value of external resistor.
