LA49101H
Overview
The LA49101H is a high-effciency 1-channel 10W BTL monaural power amplifier IC.
Increases in the number of external components are held to a minimum by adopting both a signal-following type
switching scheme in the amplifier’s output stage power supply, and a nonlinear amplifier that has nonlinear
characteristics in the signal system. The power dissipation (thermal loss) in the actual operating range has been reduced
to about 1/2 that of earlier class B amplifier ICs.
When used with the HSOP28H package, the IC dispenses with the heat sink and significantly contributes to space saving
in the end product case.
Functions
High-efficiency 10W×1ch (VCC=14V, RL=8Ω)
Encapsulated in a HSOP28H package (heat sink free)
Requires only one signal-following type switching circuit, contributing to a reduction in the number of external
components
Provides analog outputs that generate no switching noise on the output lines
Built-in standby switches (amplifier and headphone amplifier blocks)
Built-in headphone amplifier (with 1 input and 1 output)
Built-in protection circuits (shorting to the power supply, shorting to ground, and thermal protection)
