Nsiway NNSS44220033 D-Class Audio Amplifier User Manual
The NNSS44220033 is a 3 W dual‑channel D‑class audio power amplifier that offers ultra‑low EMI without the need for external filters. It uses a filter‑free PWM modulation structure, built‑in feedback resistors, and EMI‑enhancement technology to achieve high efficiency (up to 85 %) and robust protection (over‑current, over‑temperature, undervoltage). The device is supplied in an SOP16 package and operates from 3.0 V to 5.25 V.
The manual covers functional description, key features, application areas such as laptops and low‑voltage audio systems, typical application circuits, absolute maximum ratings, electrical characteristics, pin assignments, and packaging details. Guidance on layout, decoupling, and EMI mitigation is also provided to help designers integrate the amplifier into portable audio products. This manual is written in Chinese.
