Thick Film Hybrid IC
STK401-050
AF Power Amplifier (Split Power Supply)
(30 W + 30 W min, THD = 0.4%)
Overview
Now, thick-film audio power amplifier ICs are available
with pin-compatibility to permit a single PCB to be
designed and amplifier output capacity changed simply by
installing a hybrid IC. This new series was developed
with this kind of pin-compatibility to ensure integration
between systems everywhere. With this new series of IC,
even changes from 3-channel amplifier to 2-channel
amplifiers is possible using the same PCB. In addition,
this new series of ICs has a 6/3Ω drive in order to support
the low impedance of modern speakers.

[STK401-050]
STK401-000 series (2-channel/single package)
• Output load impedance RL=6Ω/3Ω supported
• New pin arrangement
To simplify input/output pattern layout and minimize
the effects of pattern layout on operational
characteristics, pin assignments are grouped into blocks
consisting of input, output and power systems.
• Few external circuits
Compared to those series used until now, boot-strap
capacitors and boot-strap resistors for external circuits
can be greatly reduced.
