AF Power Amplifier (Split Power Supply)
(20W+20W+20W, THD = 0.4%)
Overview
The STK400-030 is a 3-channel AF power amplifier IC
supporting multichannel speakers. One package includes
20W×3ch for Lch, Rch and Cch. It is pin compatible with
both 3-channel output devices (STK400-*00 series) and 2-
channel output devices (STK401-*00 series). The output
load impedance is 6/3Ω.

Features
• New series combining 3-channel output devices
(STK400-*00 series) and 2-channel output devices
(STK401-*00 series) with the same pin compatibility.
• Output load impedance is 6/3Ω.
• Pin assignment is grouped into individual blocks of
inputs, outputs and supply lines, minimizing the adverse
effects of pattern layout on operating characteristics.
• Minimum number of external components required.
