AF Power Amplifier (Split Power Supply)
(35W + 35W min, THD = 0.4%)
Overview
The STK401-060 is a thick-film audio power amplifier IC
belonging to a series in which all devices are pin compatible. This allows a single PCB design to be used to construct amplifiers of various output capacity simply by
changing hybrid ICs. Also, this series is part of a new,
larger series that comprises mutually similar devices with
the same pin compatibility. This makes possible the development of a 2-channel amplifier from a 3-channel amplifier using the same PCB. In addition, this new series
features 6/3 Ω drive in order to support the low impedance
of modern speakers.
Features
• Pin compatible
STK400-000 series (3-channel/single package)
STK401-000 series (2-channel/single package)
• Output load impedance R
• New pin configuration
Pin configuration has been grouped into individual
blocks of inputs, outputs and supply lines, minimizing
the adverse effects of pattern layout on operating characteristics.
• Few external components
In comparison with existing series, external bootstrap
resistors and capacitors can be eliminated.

Notes.
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 av er age-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.
