Product Summary
The STK412-150 is a 150w two-channel shift power supply audio power amplifier IC which is produced by Sanyo. These ICs provide 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)Maximum supply voltage(no signal): ±69V; (2)Maximum supply voltage 2 (signal present), RL = 8, 6Ω: ±62 V; (3)Maximum supply voltage 3 (signal present), RL = 4Ω: ±49 V; (4)Maximum supply voltage 1 (no signal): ±44 V; (5)Maximum supply voltage 2 (signal present): RL = 8, 6Ω: ±40 V; (6)Maximum supply voltage 3 (signal present), RL = 4 Ω: ±30 V; (7)Operating IC substrate temperature: 125℃; (8)Storage temperature:–30 to +125℃.
Features
STK412-150 features: (1)Pin compatible IC series that covers power ratings from 50 W ×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): 64 ×36.5×8.5 mm, 150 W/ch to 180 W/ch (THD = 0.7%, f = 20 Hz to 20 kHz): 78 × 44× 9 mm, Not including the IC pins; (4)Allowable load shorted time: 0.3 s.
