TDA2008

TDA2008 12W AUDIO AMPLIFIER (Vs = 22V, RL = 4Ω) DESCRIPTION The TDA2008 is a mololithic class B audio power amplifier in Pentawatt® package designed for driving low impedence loads (down to 3.2Ω). The divice provides a high output current capability(up to 3A), very low harmonic and crossover distortion. In addition,the device offers the following features: – very low number of external components; – assembly ease, due to Pentawatt® power package with no electrical insulations requirements; – space and cost saving; – high reliability; – flexibility in use; – thermal protection.
