LV1115/M
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 (AViSSTM) , 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) * AViSSTM (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
