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.
· Series of pin compatible power amplifiers ranging from × 2 channels × 2 channel (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 to 20 kHz); * 50 W/ch to 80 W/ch (THD to 20 kHz); mm * Not including the pins.· Output load impedance: 6 · Allowable load shorted time: 0.3 seconds· 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. SANYO assumes no responsibility for equipment failures that result from using products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other parameters) listed in products specifications of any and all SANYO products described or contained herein.

Notes: 1. Unless otherwise noted, use a constant-voltage supply for the power supply used during inspection. 2. 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. Use the transformer power supply circuit stipulated in the figure below for output noise voltage measurement. 3. Use the transformer power supply circuit stipulated in the figure below for allowable load shorted time measurement. DBA40C 10000µF +VCC 500
