Thick-Film Hybrid IC
STK404-140S One-Channel Class AB Audio
Power Amplifier IC 120W
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.

Notes: 1. Unless otherwise noted, use a constant-voltage supply for the power supply used during inspection.
2. The thermal sensor temperature (+125 to +145°C) is designed to prevent incorrect operation, but does not guarantee continued operation of the
hybrid IC. The total integrated time this device spends operating in the temperature range +125 to +145°C must not exceed 12 hours.
3. The output noise voltage values shown are peak values read with a VTVM. However, an AC stabilized (50Hz) power supply should be used to
minimize the influence of AC primary side flicker noise on the reading.
4. Use the transformer power supply circuit shown in the figure below for allowable load shorted time measurement and output noise voltage
measurement.This IC is designed assuming that applications will provide a load-shorting protection function that operates within 0.3 seconds of
the load being shorted and that either cuts off power to the IC or eliminates the load-shorted state in some other manner.
