STK4034X Datasheet, PDF (1/3 Pages) Sanyo Semicon Device – AF Power Amplifier (Split Power Supply) (45 W min, THD = 0.008%)

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).
