STK404-120S
Thick-Film Hybrid IC
One-Channel Class AB
Audio Power Amplifier IC 80W
Overview
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.
