The PAMS58xx series is a family of fully integrated digital input Class D amplifiers designed for high performance audio applications. Delivering up to 41 W (stereo) or 82 W (mono), this series provides exceptional sound quality, high efficiency, and design scalability—all while following a uniform PCB layout for easy integration.
Equipped with advanced digital signal processing (DSP), the PAMS58xx series enables precise and flexible audio tuning without the need for external components. Built in DSP features include.
- Equalization (EQ)
- Dynamic Range Control (DRC)
- Automatic Gain Limiter (AGL)
- Dynamic Range Boost (DRB)
To further enhance efficiency, the integrated Class H power control dynamically adjusts the supply voltage based on audio demand, reducing heat generation and extending battery life. With ultra low THD+N (0.02%) and output noise below 37 µV RMS, the PAMS58xx series delivers clean, distortion free, high fidelity audio.
The family offers over 90% efficiency, integrated tuning capabilities, and a common pinout across all five variants (PAMS5803/04/25/26/27). This allows engineers to scale power and features through firmware—simplifying development, accelerating design cycles, and reducing overall BOM cost.
