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 newlow thermal resistance substrate in these products to reduce the package size by about 60% as compared to the earlier SANYO STK407-000 series.

Package Dimensions
unit: mm 4189-SIP15
[STK402-070]

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 outputpower grade. • The pin arrangement is compatible with that of the 3channel 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.
