SANYO STK400-290 Datasheet

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)

STK401-000 series (2-channel, single package)

• Output load impedance RL=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.

Notes

• Use rated power supply for testing unless otherwise specified.

• When measuring available time for load short-circuit and output noise voltage, use transformer power supply indicated
below.

• Output noise voltage is represented by the peak value rms (VTVM) for mean reading. Use an AC stabilized power
supply (50 Hz) on the primary side to eliminate the effect of AC flicker noise.
