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 rejec-

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

tion.

Ω, 1.6W at 9V/4Ω

and 1.2W at 9V/8

Ω.
