Some sources describe the STK411-210E as having a quiescent current of 2.5uA and a Power Supply Rejection Ratio (PSRR) of 70dB at 1kHz, which enhances stability and prevents power supply noise from contaminating the audio signal.
Finding a standalone PDF for the "E" suffix specifically can be difficult, as it was often an OEM-specific part. You can view or download technical documents through these sources: Supports an external muting function to prevent "pop"

Thick-film Hybrid Integrated Circuit, combining power transistors and peripheral components within a single, heat-sinkable package. 2. STK411-210E Pinout and Schematic Layout
The STK411-210E comes in a (Single In-line Package with 18 pins) form factor. This is a multi-watt hybrid package designed to be mounted onto a heatsink. For proper thermal management, a heatsink with good thermal conductivity is essential; otherwise, thermal shutdown or permanent damage may occur at high output levels.

is a dual-channel (stereo) thick-film hybrid audio power amplifier IC engineered for high-fidelity audio gear and home theater receivers. Known for its split-power supply architecture and low total harmonic distortion (THD), this module provides a robust, single-chip alternative to building complex discrete audio amplifier stages.
