STK4042XI

Ordering number: EN1677B Thick Film Hybrid IC STK4042XI AF Power Amplifier (Split Power Supply) (80W min, THD = 0.008%) Features Small-sized package permitting audio sets to be made slimmer. The STK4018XI series are available for output 50W to 80W and are pin-compatible. Facilitates thermal design of slim stereo sets. The use of a current mirror circuit, cascode circuit, pure complementary circuit provides low distortion (0.008% / 100kHz, LPF ON). Possible to design electronic supplementary circuits (pop noise muting at the time of power ON/OFF, load short protector, thermal shutdown) Package Dimensions unit: mm 4075 [STK4042XI] Specifications Maximum Ratings at Ta = 25°C Parameter Maximum supply voltage Thermal resistance Junction temperature Operating substrate temperature Storage temperature Available time for load short-circuit Symbol VCC max θj-c Tj Tc Tstg ts*1 VCC = ±46.5V, RL = 8Ω, f = 50Hz, PO = 80W Conditions Ratings ±67 1.2 150 125 −30 to +125 1 Unit V °C/W °C °C °C s Recommended Operating Conditions at Ta = 25°C Parameter Recommended supply voltage Load resistance Symbol VCC RL Conditions Ratings ±46.5 8 Unit V Ω SANYO Electric Co., Ltd.
