Sanyo STK405-110 Specifications

Any and all SANYO products described or contained herein do not have specifications that can handle
applications that require extremely high levels of reliability, such as life-support systems, aircraft’s
control systems, or other applications whose failure can be reasonably expected to result in serious
physical and/or material damage. Consult with your SANYO representative nearest you before using
any SANYO products described or contained herein in such applications.

SANYO assumes no responsibility for equipment failures that result from using products at values that
exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges,or other
parameters) listed in products specifications of any and all SANYO products described or contained
herein.

Preliminary
Overview

The STK405-110, a member of the STK405-000 series, is
a low-cost, 2-channel audio power amplifier hybr id IC that
is ideal for a wide range of stereo sets. It has dedicated 6Ω
output drive, in contrast with the STK401-000 series which
supports 6Ω/3Ω output drive.

Features

• Class B amplifiers

• Output load impedance R

• EIAJ-output compatible (f=1kHz, THD=10%)

• Low supply switching shock noise

• Pin assignment grouped into individual blocks of
inputs, outputs and supply lines to minimize the
adverse effects of pattern layout on operating character­istics

• External boostrap circuit not necessary

• Standby operation possible using external circuit

• Voltage gain VG=26dB for easy gain distribution within
the set

• Member of 10W/ch to 80W/ch pin-compatible series

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.
