STK402-090S

2xNF-E,classAB,±54V,2x80W(2x50W/0.4%THD/±47V/6om),14-SIL,SAM

Features
• Series of pin compatible power amplifiers ranging from
20 W ´ 2 channels to 120 W ´ 2 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 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 ½
• Allowable load shorted time: 0.3 seconds
• Supports the use of standby, muting, and load shorting
protection circuits.
