STK4042II
STK4042II is AF Power Amplifier manufactured by SANYO.
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-patible 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).
