Overview
The STK402-000 series products are audio power
amplifier hybrid ICs that consist of optimally-designed
discrete component power amplifier circuits that have
been miniaturized using SANYO's unique insulated metal
substrate technology (IMST). SANYO has adopted a new
low thermal resistance substrate in these products to
reduce the package size by about 60% as compared to the
earlier SANYO STK407-000 series.
Features
• Series of pin compatible power amplifiers ranging from
20 W × 2 channels to 120 W × 2 channels (10%/1 kHz)
devices. The same printed circuit board can be used
depending on the output power grade.
• The pin arrangement is compatible with that of the 3channel STK402-200 series. This means that 3-channel
printed circuit boards can also be used for 2-channel
products.
• Miniature packages
— 15 W/ch to 40 W/ch (THD = 0.4%, f = 20 Hz to
20 kHz); 46.6 mm × 25.5 mm ×8.5 mm *
— 50 W/ch to 80 W/ch (THD = 0.4%, f = 20 Hz to
20 kHz); 59.2 mm × 31.0 mm × 8.5 mm *
*: Not including the pins.
• Output load impedance: RL= 6 Ω
• Allowable load shorted time: 0.3 seconds
• Supports the use of standby, muting, and load shorting
protection circuits.

Notes: 1. Unless otherwise noted, use a constant-voltage supply for the power supply used during inspection.
2. Use the transformer power supply circuit stipulated in the figure below for allowable load shorted time measurement and output noise voltage
measurement.

3. The output noise voltage values shown are peak values read with a VTVM. However, an AC stabilized (50 Hz) power supply should be used to
minimize the influence of AC primary side flicker noise on the reading.
