Thick Film Hybrid IC

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)
