Overview
One-Channel Class AB Audio Power Amplifier IC 50W
The STK404-000S 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 45W to 180W (10%/1kHz) devices. The same printed circuit board can be used depending on the output power grade. · Miniature packages -- 30W to 40W (THD=0.4%, f=20Hz to 20kHz); 44.0mm × 25.6mm × 8.5mm * -- 50W to 80W (THD=0.4%, f=20Hz to 20kHz); 46.6mm × 25.5mm × 8.5mm * -- 100W to 120W (THD=0.4%, f=20Hz to 20kHz); 59.2mm × 25.5mm × 8.5mm * *: Not including the pins. · Output load impedance: RL=6 · Allowable load shorted time: 0.3 seconds · Built-in thermal protection circuit · Supports the use of standby, muting, and load shorting protection circuits. Series Organization These products are organized as a series based on their output capacity.
