2-Channel 80 W min AF Power Amplifier
(Split Power Supply)
STK4221V
Features
• The inclusion of a muting circuit on-chip allows all
types of impulse noise to be excluded.
• Current mirror circuit application reduces distortion to
0.008%.
• Pin compatible with the STK4201II Series (THD = 0.4%)
and the STK4141X Series (THD = 0.02%)
