Ordering number: EN 1650B
Thick Film Hybrid IC
STK4151V
AF Power Amplifier (Split Power Supply) (30W + 30W min, THD = 0.08%)
Features
•Built-in muting circuit to cut off various kinds of pop noise.
•Greatly reduced heat sink due to substrate temperature 125°C guaranteed.
•Distortion 0.08% due to current mirror circuit.
•Pin-compatible with the STK4101II series. The STK4101V series use the same package and are available for output 6W to 50W.
•Excellent cost performance.

Note : 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 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.
