| Ordering number : EN4673A Thick Film Hybrid IC STK4034X AF Power Amplifier (Split Power Supply) (45 W min, THD = 0.008%) Features * Miniature package allows audio sets to be made slimmer. * Pin-compatible amplifiers with outputs of 30 to 100 W are available. * Facilitates thermal design of slim stereo sets by distributing the heat dissipating ICs in the set. * Current mirror circuit application reduces distortion to 0.008%. * Supports the design of supplementary electronic circuits (thermal shutdown, load short protection, and pop noise muting at power on and off).
