STK4042II Datasheet, PDF (1/3 Pages) Sanyo Semicon Device – AF Power Amplifier (Split Power Supply) (80 W min, THD = 0.4%)

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).
