SANYO LA2615M, LA2615 Datasheet

Ordering number : ENN6464

41001TN (OT) No. 6464-1/7

Overview

The LA2615 and LA2615M are sound field playback
processing ICs for use in audio equipment, TVs, and PCs.
These ICs allow equipment to easily reproduce a spatial
realistic sound field from a stereo signal from a music,
video, or other audio source.

Features

• Supports a wide operating supply voltage range, and can
be used in a wide range of applications.

• The added surround signal level can be adjusted.

• Low-noise low-distortion bypass mode

• Provides a natural feeling of spaciousness without
degrading the tonal coloration of the source.

• Clear vocal positioning without any apparent loss of
center to the sound

• Miniature packages: 16-pin DIP (LA2615) and 16-pin
MFP (LA2615M)

Functions

• Surround signal processing

• Variable surround effect

• Surround/bypass switching

• LED drive circuit
