STK403-450
Six-Channel Class AB Audio Power Amplifier IC
30 W ×6 Channels
Overview
The STK403-400 series products are audio power
amplifier hybrid ICs that consist of optimally-designed
discrete component power amplifier circuits that have
been miniaturized using SANYO’s unique insulated metal
substrate technology (IMST). The adoption of a newly-
developed low thermal resistance substrate allows this
product to integrate six power amplifier channels in a
single compact package. The adoption of a standby circuit
in this device allows it to reduce impulse noise
significantly as compared to earlier Sanyo products, in
particular, the STK402-*00 series products.

Notes: 1. 1ch drive
2. Unless otherwise noted, use a constant-voltage supply for the power supply used during inspection.
3. The output noise voltage values shown are peak values read with a VTVM. However, an AC stabilized (50 Hz) power supply should be used to
minimize the influence of AC primary side flicker noise on the reading.
4. Use the transformer power supply circuit shown in the figure below for allowable load shorted time measurement and output noise voltage
measurement.
5. Design applications so that the minus pre-VCC line (pin 17) is at the lowest potential at all times.
6. A limiting resistor that assures that the maximum operating current flowing into the standby pin (pin 23) does not exceed the maximum rating must
be included in application circuits. This IC operates when a voltage higher than VBE (about 0.6 V) is applied to the standby pin.
