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