Preliminary
Overview
The STK401-290 is a 2-channel audio power amplifier IC
that supports 6/3Ω output load impedances. It is fully pin
compatible with the 3-channel output devices (STK400×00 series) and 2-channel output devices (STK401-×00
series). In addition, it supports 6/3Ω output load impedance.
Features
• Pin compatible with the 3-channel output devices
(STK400-×00 series) and 2-channel output devices
(STK401-×00 series)
• Output load impedance RL=6/3Ω supported
• Pin configuration grouped into individual blocks of
inputs, outputs and supply lines to minimize the
adverse effects of pattern layout on operating characteristics.
• Few external components

Note.
All tests are measured using a constant-voltage supply unless otherwise specified.
Available time for load short-circuit and output noise voltage are measured using the transformer supply specified below.
The output noise voltage is the peak value of an a verage-reading meter with an rms value scale (VTVM). A regulated AC
supply (50Hz) should be used to eliminate the effects of AC primary line flicker noise.
