STK402-020

• 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 3- channel 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: R_L = 6
• Allowable load shorted time: 0.3 seconds
• Supports the use of standby, muting, and load shorting protection circuits.

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.
