Overview

The STK405-050, 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.
