® 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(splayers etc. Main features are: minimum working supply voltage of 3V, low quiescent current, low cnumber of external components, good ripple rejecution, no cross-over distortion, low power dissipadtion. roOutput power: Po = 2W at 12V/8Ω, 1.6W at 9V/4Ω Pand 1.2W at 9V/8Ω. leteABSOLUTE MAXIMUM RATINGS soSymbol Parameter bVs - OIo )Ptot t(sTstg, Tj Supply voltage Output peak current Power dissipation at Tamb = 50°C Storage and junction temperature Minidip ORDERING NUMBER: TBA820M Va [ ... ]
