Ordering number: EN4611A
Thick Film Hybrid IC
STK4221 II
AF Power Amplifier (Split Power Supply)
(80W + 80W min, THD = 0.4%)
Features
• Built-in muting circuit to cut off various kinds of pop
noise
• Current mirror circuit application reduces distortion to
0.4% (THD)
• The STK4201II series (THD=0.4%), STK4201V series
(THD=0.08%), and STK4141X series (THD=0.02%)
are pin-compatible.
