The STK400-020 is a thick-film hybrid integrated circuit (IC) audio power amplifier module manufactured by SANYO Semiconductor. This module is designed for high-fidelity audio amplification in various consumer electronics applications. It incorporates all the necessary components for a complete power amplifier stage, simplifying system design and reducing component count.

Applications

• Stereo amplifiers
• Home theater systems
• Audio receivers
• Powered speakers
• Musical instruments amplifiers

Features

• High output power (typically around 20W per channel)
• Low distortion
• Built-in protection circuits (overcurrent, thermal)
• Simplified circuit design
• Compact size
• Single power supply operation

Benefits

• High output power delivers sufficient volume for most audio applications.
• Low distortion ensures high-fidelity audio reproduction.
• Built-in protection circuits enhance reliability and prevent damage to the amplifier module and speakers.

Additional Details

The STK400-020 is typically supplied in a SIP (Single In-line Package) package. Key electrical specifications include output power, supply voltage, total harmonic distortion (THD), and input impedance. A heat sink is generally required to dissipate heat generated during operation. The device's datasheet provides detailed information on these parameters and application guidelines.
