Overview
Surround Processor ICs for Electronic Volume Control
The LV1115/M are a sound processor ICs developed for use in TV sets.
They incorporate surround processing function (AViSS™) , pseudo stereo function, auto gain control, and the major functional blocks of an electronic volume control IC.
Functions
• 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]) • Master 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 control) • Auto gain control function • I2C bus control
