The audio speaker experience is one of the core competencies of consumer electronic terminals. With the large-scale adoption and popularity of silicon anode batteries, terminal devices have higher comprehensive requirements for audio amplifiers regardingbattery compatibility, speaker loudness, and playback battery life.In response to industry development trends, awinic has launchedAWA87396FCR / AWA87397FCRa new generationSmart Kof analog audio power amplifiers, achieving comprehensive upgrades in three key dimensions: battery adaptation, output power, and work efficiency, providing higher-performance analog audio solutions for terminals such as smartphones and smart wearables.
The new generationAWA87396FCR/AWA87397FCRbuilds upon core features such as low noise, low distortion, and comprehensive speaker protection, achieving three major breakthroughs:UVLOas low as2V, deeply adapting to silicon anode batteries to fully release battery capacity; output power increased by20%, with power consumption further optimized by8%or more,powering next-generation terminals in creating high-quality audio experiences with stronger performance and better energy efficiency.
Key Product Features
Fully adapted to silicon anode batteries, fully releasing the benefits of battery capacity
With the rapid popularization of silicon anode battery technology, the battery discharge cutoff voltage has further decreased, posing a severe test for the low-voltage working capability of power link devices. The current shutdown voltage has dropped to2.7Vbelow, and the amplifier'sUVLOvoltage must also be less than2.2V.
AWA87396FCR/AWA87397FCRIt can perfectly compatible the wide discharge range of silicon anode batteries, with aUVLOvoltage as low as 2.0V, comprehensively supporting various types of silicon anode batteries, fully excavating available battery capacity. Even when the terminal device has low battery, it can still ensure normal audio speaker output, avoiding issues such as abnormal sound at low battery levels.
Significantly increased output power, delivering more powerful speaker loudness
Output power is comprehensively enhanced, increasing by20%, and call loudness is improved by1~2dB:
Higher output power can drive speakers to achieve louder speaker volume, increasing the overall loudness reserve. In scenarios such as short video playback, audio-visual entertainment, and hands-free calls, the sound is loud and clear; combined withawinic's self-developedMulti‑Level AGC, it suppresses clipping distortion at high volumes, balancing loudness with pure sound quality, ensuring clear hearing even in noisy environments.
Comprehensive optimization of overall device efficiency, reducing song playback power consumption by 8% or more
The new products deeply optimize the collaborative working mechanism of the charge pump and power stage for the typical operating range of music playback, comprehensively upgrading the overall conversion efficiency. In actual song playback scenarios, power consumption is optimized by8%or more compared to the previous generation. Lower audio playback power consumption directly translates into benefits for overall device battery life. When users listen to music or browse videos, it reduces power loss in the audio path, effectively extending usage time in audio scenarios without changing battery hardware, alleviating battery life pressure on mobile terminals.
Typical Application Scenarios
AWA87396FCR / AWA87397FCR Aimed at devices such as smartphones, tablets, smart wearables, and portable intelligent terminals, it is especiallysuitable for projects adopting silicon anode batteries, pursuing greater speaker loudness, and focusing on audio battery life performance.
awinic continues to deepen its cultivation in the audio sector, focusing on actual terminal pain points such as battery evolution, sound quality and loudness, battery life and power consumption, and reliability, constantly iterating itsSmart‑KintelligentKClass amplifier product matrix, providing consumer electronics customers with rich and rapidly deployable audio chip solutions. In the future, awinic will continue to base itself on real terminal needs, continuously delivering high-performance analog and mixed-signal chips, helping domestic terminal audio experiences to continuously break through upwards.
