Thick-Film Hybrid IC

Overview

The STK412-000 series are class H audio power amplifierhybrid ICs that feature a built-in shift power supplycircuit. These ICs provide high efficiency audio poweramplification by controlling (switching) the supplyvoltage supplied to the power transistors according to the

detected level of the input audio signal.

Package Dimensions

unit: mm4196-SIP18

Features

Pin compatible IC series that covers power ratings from50 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 acommon PCB for all output classes.

The pin arrangement is also unified with that of thethree-channel STK413-000 series. This means that PCBsdesigned for three-channel models can also be used fortwo-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 to20 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).
