Any and all SANYO Semiconductor products described or contained herein do not have specifications
that can handle applications that require extremely high levels of reliability, such as life-support systems,
aircraft's control systems, or other applications whose failure can be reasonably expected to result in
serious physical and/or material damage. Consult with your SANYO Semiconductor representative
nearest you before using any SANYO Semiconductor products described or contained herein in such
applications.
SANYO Semiconductor assumes no responsibility for equipment failures that result from using products
at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition
ranges, or other parameters) listed in products specifications of any and all SANYO Semiconductor
products described or contained herein.
LA4901
Overview
The LA4901 is a high-effciency 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 DIP-28HC package, the IC dispenses with the heat sink and significantly contributes to space saving in
the end product case.
Functions and Features
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 1 input and 1 output (VG = 6dB, PO = 60mW)
Built-in protection circuits (overvoltage and thermal protection circuits)
