TDA2008
12W AUDIO AMPLIFIER Vs = 22V/ RL= 4ohm
TDA200812W AUDIO AMPLIFIER (Vs= 22V, RL =4Ω)
DESCRIPTIONThe TDA2008isa mololithic classB audio power
amplifierin Pentawatt package designedfor driv-
inglowimpedenceloads (downto3.2Ω). Thedivice
providesa high outputcurrent capability(up to3A),
very low harmonic and crossover distortion. addition,the device offers the following features: very low numberof external components; assemblyease, dueto Pentawatt power
package withno electrical insulationsre-
quirements; space and cost saving; high reliability; flexibilityin use; thermal protection.
