STK4152II Datasheet Preview


Ordering number: EN2202B
Thick Film Hybrid IC
STK4152II
AF Power Amplifier (Split Power Supply)
(30W + 30W min, THD = 0.4%)
Features
• The STK4102II series (STK4152II) and STK4101V
series (high-grade type) are pin-compatible in the out-
put range of 6W to 50W and enable easy design.
• Small-sized package whose pin assignment is the same
as that of the STK4101II series
• Built-in muting circuit to cut off various kinds of pop
noise
• Greatly reduced heat sink due to substrate temperature
125°C guaranteed
• Excellent cost performance

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 shorte-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.
