What you get: Two (2) SMD audio amplifier ICs in one pack. Available models include CS8573E, CS8622E, CS8623E, and CS8655E. The CS8623E is included among the model options. Core function: Compact surface-mount audio amplifiers designed to provide audio amplification for consumer and professional electronic circuits. Package and mounting: Supplied in SOP16 or ESOP16 surface-mount packages, compatible with standard SMD assembly processes and common 16-pin PCB footprints. Why you need it: Fast replacement or repair of audio circuits without redesigning the board — drop-in compatibility with SOP16/ESOP16 footprints. Small footprint saves board space for compact or portable products. Two-piece quantity is convenient for prototyping, duplication of channels, or repairing two related devices. Problem solving: Eliminates the need to source single, hard-to-find chips for repairs — this pack gives a direct, ready-to-place solution. Helps accelerate development cycles by providing matched spare parts for testing and validation. Surface-mount format reduces manual soldering time and supports automated production workflows. Key attributes: Function: Audio amplification (designed for use in audio signal chains). Compatibility: SOP16 and ESOP16 standard PCB footprints and surface-mount assembly equipment. Size: Compact SMD form factor ideal for space-constrained designs. Performance: Engineered for typical audio amplification tasks — suitable for speaker drivers, preamps, and signal conditioning (refer to specific model datasheets for electrical characteristics). Practical applications: Portable speaker and Bluetooth audio modules — compact amplifiers for driving small speakers. Consumer electronics repair — replacement ICs for TVs, set-top boxes, or stereo equipment using SOP16/ESOP16 audio amp footprints. DIY and prototype audio projects — quick integration into development boards or custom PCBs for testing and demonstration. Use tips: Verify the specific model number (CS8573E, CS8622E, CS8623E, or CS8655E) against your circuit’s electrical requirements and pinout before assembly. Follow recommended PCB layout and thermal management guidance from the selected model’s datasheet for reliable operation. Two units, standard SOP16/ESOP16 SMD packages, and four supported model numbers provide a practical, space-saving option for audio amplification needs in repairs, prototyping, and small-scale production.
