LV4901H
Overview
Buit-in 80mW Headphone amplifier
BTL 10Wx2ch Crass-D Audio Power Amplifier
The LV4901H is a 10W per channel stereo digital power amplifier that takes analog inputs. The LV4901H uses unique SANYO-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
* Supports circuit designs that do not require output LC filters * BTL output, class D amplifier system * Unique SANYO-developed feedback technology achieves superb audio quality * High-efficiency class D amplifier, Low EMI * Soft muting function reduces impulse noise at power on/off * Full complement of built-in protection circuits : overcurrent protection, thermal protection, and low power supply voltage protection circuits * Built in boot strap diode * Built in Headphone amplifier
Functions
* 10W output (VD = 12V, RL = 8, THD + N = 10%) * Efficiency : > 85% (VD = 12V, RL = 8, fin = 1kHz, PO = 10W) * 80mW Stereo Headphone amplifier (VD = 12V, RL = 16, THD + N = 10%) * Package HSOP-36
