Thick-Film Hybrid IC
Six-Channel Class AB Audio Power Amplifier IC
25 W × 6 Channels
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.
• 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 *
*: Not including the pins.
• Output load impedance: RL = 6 Ω
• Allowable load shorted time: 0.3 seconds
• Supports the use of standby and muting circuits.
