Product Summary
The STK412-150 is a class H audio power amplifier hybrid IC that features a built-in shift power supply circuit. The STK412-150 provides high efficiency audio power amplification by controlling (switching) the supply voltage supplied to the power transistors according to the detected level of the input audio signal.
Parametrics
STK412-150 absolute maximum ratings: (1)VH: Maximum supply voltage 1 (no signal): ±95 V; (2)VH: Maximum supply voltage 2 (signal present): ±85 V; (3)VL: Maximum supply voltage 1 (no signal): ±61 V; (4)VL: Maximum supply voltage 2 (signal present): ±55 V; (5)VH-VL: Maximum supply voltage: 60 V; (6)Thermal resistance: 1.4 ℃/W; (7)Junction temperature: 150 ℃; (8)Operating IC substrate temperature: 125 ℃; (9)Storage temperature: -30 to +125 ℃; (10)Allowable load shorted time: 0.3 s.
Features
STK412-150 features: (1)Pin compatible IC series that covers power ratings from 50 W x 2 channels to 180 W ?2 channels at 0.7 or 0.8% THD, 20 Hz to 20 kHz. This allows the use of a common PCB for all output classes; (2)The pin arrangement is also unified with that of the three-channel STK413-000 series. This means that PCBs designed for three-channel models can also be used for two-channel models; (3)Miniature package: 50 W/ch to 120 W/ch (THD = 0.8%, f = 20 Hz to 20 kHz): 64x36.5x8.5 mm*, 150 W/ch to 180 W/ch (THD = 0.7%, f = 20 Hz to 20 kHz): 78x44x9 mm*; (4)Allowable load shorted time: 0.3 s.
