Bi-CMOS IC
LV1117N/NV
Overview
Surround Processor ICs for
Electronic Volume Control
The LV1117N/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 SW (4ch stereo inputs [L, R]). • Line out (through output). • Input gain control (−6dB, −4dB, 0dB, 4dB, 6dB: 5 positions). • AViSS (ON/OFF/6-stage level control). • Tone control (BASS: ±20dB, TREBLE: ±18dB [in 2dB steps]). • Volume control (0dB to −14dB: 1dB step/−14dB to −80dB: 2dB steps/−∞=−82dB). • Balance control. • Through mode/Mute mode. • Pseudo stereo function (ON/OFF/MONO).
