Description
This is AF Power Amplifier. Ordering number : EN4479A
Thick Film Hybrid IC
STK4042 II
AF Power Amplifier (Split Power Supply) (80 W min, THD = 0.4%)
Features
Miniature package allows audio sets to be made slimmer. Pin-compatible amplifiers with outputs of 20 to 200 W are available. Facilitates thermal design of slim stereo sets by distributing the heat dissipating ICs in the set. The adoption of constant current circuits reduces pop noise when the power supply is turned on or off. Supports the design of supplementary electronic circuits (thermal shutdown, load short protection, and pop noise muting at power on and off).
