12W AUDIO AMPLIFIER (Vs= 22V, RL=4Ω)
DESCRIPTION
The TDA2008 is a mololithic class B audio power
amplifierin Pentawatt
inglowimpedenceloads(downto3.2Ω).Thedivice
providesa highoutputcurrentcapability(up to 3A),
verylow harmonic and crossoverdistortion.
In addition,thedeviceoffersthefollowingfeatures:
– very lownumber of external components;
– assemblyease,due to Pentawatt
packagewith no electrical insulationsre-
quirements;
– spaceand cost saving;
– high reliability;
– flexibilityin use;
– thermalprotection.
