STK4026II Datasheet | SANYO

Ordering number : EN4549A Thick Film Hybrid IC .. STK4026 II AF Power Amplifier (Split Power Supply) (25 W min, THD = 0.4 %) Features - pact packaging supports slimmer set designs - Series designed for 20 up to 200 W and pinpatibility - Simpler heat sink design facilitates thermal design of slim stereo sets - The pulse noises associated with turning the power on and off have been reduced by the adoption of fixed current circuits - Supports addition of electronic circuits for thermal shutdown and load-short protection circuit as well as pop noise muting which occurs when the power supply switch is turned on and off Specifications Maximum Ratings at Ta = 25°C Parameter Maximum supply voltage Thermal resistance Junction temperature Operating substrate temperature Storage temperature Available time for load shorted Symbol VCC max θj-c Tj Tc Tstg t S- 1 VCC = ±26 V, RL = 8 Ω, f = 50 Hz, PO = 25 W Conditions Ratings ±38 2.4 150 125 - 30 to +125 2 Unit V °C/W °C °C °C s Remended Operating Conditions Ta = 25°C Parameter Remended supply voltage Load resistance Symbol VCC RL Conditions Ratings ±26 8 Unit V Ω Operating Characteristics at Ta = 25°C, VCC = ±26 V, RL = 8 Ω, VG = 40 d B, Rg = 600 Ω, RL (noninductive) Parameter Quiescent current Output power Total harmonic distortion Frequency response Input resistance Output noise voltage Neutral voltage Symbol ICCO PO (1) PO (2) THD f L, f H ri VNO - 2 VN VCC = ±30 V THD = 0.4%, f = 20 Hz to 20 k Hz VCC = ±22 V, THD = 1.0%, RL = 4 Ω, f = 1 k Hz PO = 1.0 W, f = 1k Hz PO = 1.0 W, +0 d B - 3 PO = 1.0 W, f = 1k Hz VCC = ±30 V, Rg = 10 kΩ VCC = ±30 V - 70 0 20 to 50k 55 1.2 +70 Conditions Ratings min 10 25 25 0.3 typ 20 max 50 Unit m A W W % Hz kΩ m Vrms m V Note: Use rated power supply for test unless otherwise specified. 1.
