Product Summary
The STK433-270 is a hybrid IC designed to be used in 80W × 3ch class AB audio power amplifiers. Its application is audio power amplifier.
Parametrics
Absolute maximum ratings: (1)Maximum power supply voltage, VCC max(0): ±54V, condition: Non signal ; (2)Maximum power supply voltage, VCC max(1): ±47V, condition: RL≥6Ω; (3)Minimum operating supply voltage, VCC min: ±10V; (4)13 Operating voltage, VST OFF max: -0.3 to +5.5V; (5)Thermal resistance, θj-c: 2.1℃/W, condition: Per one power transistor; (6)Junction temperature, Tj max: 150℃, condition: Should satisfy Tj max and Tc max; (7)Operating substrate temperature, Tc max: 125℃, condition: Should satisfy Tj max and Tc max; (8)Storage temperature, Tstg: -30 to +125℃; (9)Allowable time for load short-circuit, ts: 0.3 s, condition: VCC=±33V, RL=6Ω, f=50Hz, PO=50W, 1-channel active.
Features
Features: (1)Pin-to-pin compatible outputs ranging from 80W to 150W; (2)Can be used to replace the STK433-000/-100 series (30W to 150W×2ch) and STK433-200(A) series (30W to 60W×3ch) due to its pin compatibility.; (3)Miniature package (64.0mm×36.6mm×9.0mm); (4)Output load impedance: RL = 6Ω to 4Ω supported; (5)Allowable load shorted time: 0.3 second; (6)Allows the use of predesigned applications for standby and mute circuits.
