Thick-Film Hybrid IC

STK402-240
Three-Channel Class AB Audio Power Amplifier IC 25 W + 25 W + 25 W

Overview
The STK402-200 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 STK408-000 series.

Package Dimensions
unit: mm 4191-SIP19
[STK402-240]

Features
· Series of pin compatible power amplifiers ranging from 20 W × 3 channels to 60 W × 3 channels (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 2channel STK402-000 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); 59.2 mm × 31.0 mm × 8.5 mm * *: Not including the pins. · Achieves superlative heat dissipation due to the adoption of SANYO's Insulated Metal Substrate Technology (IMST). · Output load impedance: RL = 6 · Allowable load shorted time: 0.3 seconds · Supports the use of standby, muting, and load shorting protection circuits.
