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 frequencyclass 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 Minidip number of external components, good ripple rejec- tion, no cross-over distortion, low power dissipa- tion. ORDERING NUMBER: TBA820M Output power: Po = 2W at 12V/8Ω, 1.6W at 9V/4Ω and 1.2W at 9V/8Ω.
