Two-Channel Shift Power Supply Audio Power Amplifier ICs
50W + 50 W
Overview
Package Dimensions
The STK412-000 series are class H audio power amplifier
hybrid ICs that feature a built-in shift power supply
circuit. These ICs provide high efficiency audio power
amplification by controlling (switching) the supply
voltage supplied to the power transistors according to the
detected level of the input audio signal.

Features
• Pin compatible IC series that covers power ratings from
50 W × 2 channels to 180 W × 2 channels at 0.7 or 0.8%
THD, 20 Hz to 20 kHz. This allows the use of a
common PCB for all output classes.
• The pin arrangement is also unified with that of the
three-channel STK413-000 series. This means that PCBs
designed for three-channel models can also be used for
two-channel models.

Notes: *1. Unless otherwise specified, a constant-voltage power supply must be used during inspection.
*2. The output noise voltage rating gives the peak value read by an averaging VTVM. However, to eliminate the influence of flicker noise from the AC
primary side line, use an AC stabilized power supply (50 Hz).

*3. Use the transformer power supply specified in the figure below for allowable load shorted time and output noise voltage measurements.
*4. Design circuits so that (|VH| - |VL|) is always less than 40 V when switching the power supply with the load connected.
*5. Set up the VL power supply with an offset voltage at power supply switching (VL - LO) of about 8 V as an initial target.
