Features: • Series of pin compatible power amplifiers ranging from 20 W*3 channels to 60 W*3 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 2- channel STK402-000 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); 59.2 mm *31.0 mm *8.5 mm *
*: Not including the pins.
• Achieves superlative heat dissipation due to the adoption of SANYO's Insulated Metal Substrate Technology (IMST).
• Output load impedance: RL = 6
• Allowable load shorted time: 0.3 seconds
• Supports the use of standby, muting, and load shorting protection circuits.Specifications

DescriptionThe STK402-270 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 STK408-000 series.
The STK402-270 has the following features include:(1)series of pin compatible power amplifiers ranging from 20 W *3 channels to 60 W *3 channels (10%/1 kHz) devices.The same printed circuit board can be used depending on the output power grade.;(2)the pin arrangement is compatible with that of the 2-channel STK402-000 series.This means that 3-channel printed circuit boards can also be used for 2-channel products.;(3)allowable load shorted time: 0.3 seconds;(4)supports the use of standby, muting, and load shorting protection circuits.Any and all SANYO products described or contained herein do not have specifications that can handle applications that require extremely high levels of reliability, such as life-support systems, aircraft's control systems, or other applications whose failure can be reasonably expected to result in serious physical and/or material damage. Consult with your SANYO representative nearest you before using any SANYO products described or contained herein in such applications.
The absolute maximum ratings of the STK402-270 are:(1)junction temperature:150°C;(2)storage temperature: -30 to +125°C;(3)maximum supply voltage:±50 V;(4)termal resistance:- 3.1°C/W.Specifications of any and all SANYO products described or contained herein stipulate the performance,characteristics, and functions of the described products in the independent state, and are not guarantees of the performance, characteristics, and functions of the described products as mounted in the customer's products or equipment. To verify symptoms and states that cannot be evaluated in an independent device, the customer should always evaluate and test devices mounted in the customer's products or equipment.Any and all information described or contained herein are subject to change without notice due to product/technology improvement, etc. When designing equipment, refer to the "Delivery Specification" for the SANYO product that you intend to use.
