61197HA (ID) / 8298MO / 4015MY, TS No. 1650--1/5
Ordering number: EN 1650B
Thick Film Hybrid IC
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 avail-
able for output 6W to 50W.
Excellent cost performance.

Specified transformer power supply
(Equivalent to RP-25)
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.
