Thick Film Hybrid IC
STK4141V AF Power Amplifier (Split Power Supply) (25W + 25W min, THD = 0.08%)
Features
· The STK4102II 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 repuirements for new sets simply by changing the IC. · Built-in muting circuit to cut off various kinds of pop noise. · Greatly reduced heat sink due to substrate temperature 125°C guaranteed. · 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 available time for load short-circuit and output noise voltage, use the specified transformer power supply shown below. 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.
