Product Summary
The STK412－240 is a class H audio power amplifier hybrid ICs that feature a built－in Shift power supply circuit. The STK412－240 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
STK412－240 absolute maximum ratings: (1) VL: Maximum supply voltage 3 (signal present) VL max(3) RL = 4 Ω : ±30 V; (2) VH－VL: Maximum supply voltage *4 VH－L max No load: 60 V; (3) Thermal resistance qj－c Per power transistor: 1.9 ℃/W; (4) Junction temperature Tj max Both the Tjmax and Tcmax conditions must be met.: 150 ℃; (5) Operating IC substrate temperature Tc max Both the Tjmax and Tcmax conditions must be met.: 125 ℃; (6) Storage temperature Tstg ?0 to +125 ℃; (7) Allowable load shorted time *3 ts VH = ±43 V, VL = ±30 V, RL = 8 Ωf = 50 Hz, PO = 70 W, one channel operating: 0.3 s.
Features
STK412－240 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.
