常見問題解答

What is AK5392-VS?

The AK5392-VS is a high-performance 24-bit stereo analog-to-digital converter (ADC) designed by AKM Semiconductor. It is well-suited for professional audio recording applications, digital audio workstations, and high-fidelity audio equipment.

How Does AK5392-VS Work?

The AK5392-VS works by converting analog audio signals from stereo inputs into digital data with high precision and dynamic range. It employs advanced delta-sigma modulation and oversampling techniques to achieve high-resolution audio conversion. The converter features selectable digital filter settings to optimize audio performance based on the application requirements.

How Many Pins does AK5392-VS have and What are the Functions of the Pinout Configuration?

The AK5392-VS is housed in a 28-pin SSOP (Shrink Small Outline Package) package. The pinout configuration includes:

  • DVDD, AVDD: Digital and analog power supply pins, respectively.
  • DGND, AGND: Digital and analog ground pins, respectively.
  • LRCK, BICK, SDTI, SDTO: Serial audio interface pins for left/right clock, bit clock, serial data input, and serial data output, respectively.
  • MD0-MD2: Mode control pins for configuring the digital filter settings and other operating modes.
  • AINL, AINR: Analog input pins for left and right audio channels.
  • FSYNC: Frame synchronization pin for the serial interface.
  • MCLK: Master clock input for synchronization.

What are the Pros and Cons of AK5392-VS?

Pros:

  • High Resolution: Provides 24-bit resolution for professional audio recording and playback.
  • Low Noise: Delivers high signal-to-noise ratio and low distortion for high-fidelity audio.
  • Selectable Digital Filters: Offers flexibility in optimizing audio performance based on specific audio applications.
  • Wide Dynamic Range: Provides a wide dynamic range suitable for capturing subtle audio details.
  • Suitable for Professional Audio: Designed to meet the demands of professional audio recording and playback systems.

Cons:

  • Complex Interface: Requires careful attention to the digital interface and clocking for optimal performance.
  • External Components: May need additional external components such as anti-aliasing filters and output amplifiers for complete audio signal chain.
  • Cost: High-performance audio converters like the AK5392-VS may have higher cost compared to standard audio ADCs.

Are There Any Equivalents/Alternatives to AK5392-VS for Recommendation?

  • The PCM1804 from Texas Instruments is a comparable 24-bit audio ADC with similar performance characteristics.
  • Alternatives to the AK5392-VS include the CS5361 from Cirrus Logic and the WM8786 from Cirrus Logic.
