Thick-Film Hybrid IC
STK402-070
Two-Channel Class AB Audio Power Amplifier IC
40W + 40W
Overview
The STK402-000 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). SANYO has adopted a new low thermal resistance substrate in these products to reduce the package size by about 60% as compared to the earlier SANYO STK407-000 series.
Features
•Series of pin compatible power amplifiers ranging from 20 W × 2 channels to 120 W × 2 channel (10%/1 kHz)
devices. The same printed circuit board can be used depending on the output power grade.
•The pin arrangement is compatible with that of the 3- channel STK402-200 series. This means that 3-channel printed circuit boards can also be used for 2-channel products.
•Miniature packages
—15 W/ch to 40 W/ch (THD = 0.4%, f = 20 Hz to 20 kHz); 46.6 mm × 25.5 mm × 8.5 mm *
—50 W/ch to 80 W/ch (THD = 0.4%, f = 20 Hz to 20 kHz); 59.2 mm × 31.0 mm × 8.5 mm *
*: Not including the pins.
•Output load impedance: RL = 6 Ω
•Allowable load shorted time: 0.3 seconds
•Supports the use of standby, muting, and load shorting protection circuits.

Notes: 1. Unless otherwise noted, use a constant-voltage supply for the power supply used during inspection.
2.The output noise voltage values shown are peak values read with a VTVM. However, an AC stabilized (50 Hz) power supply should be used to minimize the influence of AC primary side flicker noise on the reading.
Use the transformer power supply circuit stipulated in the figure below for output noise voltage measurement.
3.Use the transformer power supply circuit stipulated in the figure below for allowable load shorted time measurement.
