Click Suppressor: An Engineering Breakthrough in the Art of Silence  

Representative models: SSM2167 (low-power type), AD2428 (multi-channel array)  

- Technology Kernel:  

  - Adopts dynamic threshold detection technology to eliminate transient noise (<1μV residual voltage) during on/off/mode switching.  

  - Integrated adaptive filtering algorithm for smooth sensorless transition in the -40dB to +26dB gain range.  

- Scene Innovation:  

  - TWS headphones: Eliminate the ‘ticking’ sound when the in-ear detection sensor is triggered, enhancing the user experience premium of high-end models.  

  - In-vehicle audio-visual: Matching the action sequence of the high-voltage relay of the electric car, eliminating the noise interference of 12V-48V power switching.  

Volume control device: precision controller for intelligent sound field  

Flagship products: AD5262 (256-level digital potentiometer), AD8403 (four-channel high-precision attenuator)  

- Peak performance:  

  - 0.5dB step accuracy, support I²C/SPI dual-mode control, response speed up to 0.1ms.  

  - Temperature drift coefficient as low as 5ppm/°C, adaptable to -55°C to +125°C industrial grade environment.  

- Cross-border applications:  

  - Professional mixing console: 128-channel track independent gain fine-tuning via MIDI protocol.  

  - Smart home: linked AI voiceprint recognition, automatically matching the best listening loudness curve for the elderly/children.  

Audio Codec: Balancing act of high fidelity and low power consumption  

Phenomenal chips: ADAU1772 (24-bit 192kHz Hi-Res), ADAU1466 (DSP+Codec system on chip)  

- Technical Milestones:  

  - Signal-to-Noise Ratio (SNR) exceeds 120dB, THD+N as low as -105dB (@1kHz).  

  - Integrated Arm Cortex-M4 core supports Audinate Dante protocol native parsing.  

- Industry empowerment:  

  - Spatial Audio: Dynamic Head Tracking (HRTF) rendering through 6-axis IMU data fusion.  

  - Hearing aid devices: AI ambient sound classification technology reduces power consumption to 0.8mW and improves endurance by 3x.
