2-Channel 70 W min AF Power Amplifier
(Split Power Supply)
STK4211V
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%)

Operating Characteristics at Ta = 25°C, VCC= ±43 V, RL= 8 Ω (noninductive load), RG= 600 Ω, VG = 40 dB
Note: Use a constant voltage power supply as the test power supply unless otherwise specified.
* The output noise voltage is the peak value measured with an averaging rms scale volt meter. The noise voltage waveform should not include
pulse noise.
