STK400-290
AF Power Amplifier (Split Power Supply)
(50 W + 50 W + 50W min, THD = 0.08%)
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 ICs,
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.
Features
• Pin-compatible
STK400-000 series (3-channel, single package)
Package Dimensions
unit: mm
4086A
[STK400-290]
STK401-000 series (2-channel, single package)
• Output load impedance R_L=6Ω/3Ω supported
• New pin assignment
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, capacitors and
bootstrap resistors for external circuits can be greatly
reduced.
