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

t(s players etc. Main features are: minimum working

supply voltage of 3V, low quiescent current, low

c number of external components, good ripple rejec-

u tion, no cross-over distortion, low power dissipa-

d tion.

ro Output power: Po = 2W at 12V/8Ω, 1.6W at 9V/4Ω

P and 1.2W at 9V/8Ω.
