STK4042 XI
AF Power Amplifier (Split Power Supply)
(80W min, THD = 0.008%)
Features
• Small-sized package permitting audio sets to be made
Package Dimensions
unit: mm
slimmer.

[STK4042 XI ]
• 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)

Notes. For power supply at the time of test, use a constant-voltage power supply
unless otherwimse specified.
*1 For measurement of the available time for load short-circuit and output
noise voltage, use the specified transformer power supply shown below.
*2 The output noise voltage is represented by the peak value on the rms
scale (VTVM) of average value indicating type. The noise voltage waveform includes no flicker noise.
