Overview
The STK404-000 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). The adoption of a newly-
developed low thermal resistance substrate allows this
series of devices to be provided in miniature packages
significantly more compact than earlier Sanyo products
with similar specifications.
Features
• Series of pin compatible power amplifiers ranging from
• Miniature packages
• Output load impedance: R
• Allowable load shorted time: 0.3 seconds
• Supports the use of standby, muting, and load shorting
45 W to 180 W (10%/1 kHz) devices. The same printed
circuit board can be used depending on the output power
grade.
