Overview

The LV49152V is a 15W per channel stereo digital power amplifier that takes analog inputs. The LV49152V uses

unique Our developed feedback technology to achieve excellent audio quality despite being a class D amplifier and can

be used to implement high quality flat display panel (FDP) based systems.

Features

• BTL output, class D amplifier system

• Unique Our developed feedback technology achieves superb audio quality

• High-efficiency class D amplifier

• Soft muting function reduces impulse noise at power on/off

• Full complement of built-in protection circuits : over current protection, thermal protection, and low power supply

voltage protection circuits

• Built in Power limiter

Functions

• Power : 15W × 2ch output (VD = 15V, RL = 8Ω, fin = 1kHz, AES17, THD + N = 10%)

• Efficiency : 93% (VD = 15V, RL = 8Ω, fin = 1kHz, PO = 15W)

• THD + N : 0.08% (VD = 15V, RL = 8Ω, fin = 1kHz, PO = 1W, Filter : AES17)

• Noise : 90μVrms (Filter : A-weight)

• Package SSOP44J (275mil)
