LA4915
Overview
The LA4915 is a BTL two-channel power amplifier for use in TV audio systems. 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 DIP-28HC package, the IC dispenses with the heat sink and significantly contributes to space saving in
the end product case.
Functions
High-efficiency 5W+5W power amplifier
Encapsulated in a DIP-28HC 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 2 inputs and 2 outputs (VG=6dB, PO=30mW)
Built-in protection circuits (overvoltage and thermal protection circuits)
Applications
Audio output for TV application
