The STK411-210E is a thick-film hybrid integrated circuit (IC) manufactured by Sanyo, specifically designed as a 2-channel AF power amplifier for split power supply applications. It is part of the broader STK411-200 series, which is known for its pin compatibility and ease of design in audio amplification systems. Core Specifications
Based on technical data available from Scribd and Alldatasheet, the key characteristics include: Application: 2-channel (stereo) audio power amplification. Power Supply: Designed for split (dual) power supplies ( ±plus or minus Vcc). Total Harmonic Distortion (THD): Typically around (depending on specific operating conditions).
Output Power Range: The series typically covers a range from 6W to 50W per channel, allowing for design flexibility across different models.
Pin Compatibility: It is part of the STK4102II and STK4101V series, meaning these ICs can often be interchanged on the same PCB layout. Reference Resources stk411210e datasheet
