TBA820M

1.2WAUDIOAMPLIFIER

DESCRIPTION

The TBA820M is a monolithic integrated audio
amplifierin a 8 lead dual in-line plastic package.It
is intended for useas lowfrequencyclassB power
amplifier with wide range of supply voltage: 3 to
16V, in portable radios, cassette recorders and
players etc. Main features are: minimum working
supply voltage of 3V, low quiescent current, low
numberof externalcomponents,goodripple rejec­tion, no cross-over distortion, low power dissipa­tion.
Outputpower: P

=2W at 12V/8Ω, 1.6W at9V/4Ω
