Features
• The STK4201II series (THD=0.4%), STK4201V series
(THD=0.08%) and STK4141X series (THD=0.02%)
are pin-compatible. Once the PCB pattern is designed,

you can easily satisfy the requirements for new sets simply by changing the IC.
• Built-in muting circuit to cut off various kinds of pop
noise.
• Current mirror circuit application reduces distortion to
0.08%.

Notes.
For power supply at the time of test, use a constant-voltage power supply unless
otherwise specified.
For measurement of the availab le time for load short-circuit and output noise voltage, use the specified transformer power supply shown right.
The output noise voltage is represented by the peak value on rms scale (VTVM)
of average value indicating type. For AC power supply, use an AC stabilized
power supply (50Hz) to eliminate the effect of flicker noise in AC primary line.
