Thick-Film Hybrid IC

STK412-030

Two-Channel Shift Power Supply Audio Power Amplifier ICs 100W + 100 W

Overview

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.

•Miniature package

—50 W/ch to 120 W/ch (THD = 0.8%, f = 20 Hz to 20 kHz): 64 × 36.5× 8.5 mm*

—150 W/ch to 180 W/ch (THD = 0.7%, f = 20 Hz to 20 kHz): 78 × 44× 9 mm*

*Not including the IC pins.

•Allowable load shorted time: 0.3 s

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).
