TBA820M
®
1.2W AUDIO AMPLIFIER
DESCRIPTION
The TBA820M is a monolithic integrated audio
amplifier in a 8 lead dual in-line plastic package. It
is intended for use as low frequency class B 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
number of external components, good ripple rejection, no cross-over distortion, low power dissipation.
Output power: Po = 2W at 12V/8Ω, 1.6W at 9V/4Ω
and 1.2W at 9V/8Ω.
