Overview
The STK403-400 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).  The adoption of a newly developed low thermal resistance substrate allows this product to integrate six power amplifier channels in a
single compact package. The adoption of a standby circuit in this device allows it to reduce impulse noise significantly as compared to earlier Sanyo products, in particular, the STK402-*00 series products.

FEATUREs
• Series of pin compatible power amplifiers ranging from 30 W/ch to 45 W/ch (10%/1 kHz) devices. The same printed circuit board can be used depending on the output power grade.
• Miniature packages
— 78.0 mm ×32.0 mm ×9.0 mm
• Output load impedance: RL= 6 Ω
• Allowable load shorted time: 0.3 seconds
• Supports the use of standby and muting circuits.
