FAQs

What is AK4528VF?

The AK4528VF is a high-performance 24-bit stereo analog-to-digital/digital-to-analog converter (ADC/DAC) designed by Asahi Kasei Microdevices. It is suitable for professional audio recording and playback applications, offering high-resolution conversion and low distortion performance.

How Does AK4528VF Work?

The AK4528VF operates as a stereo ADC and DAC, converting analog audio signals to digital data and vice versa with high precision. It utilizes a delta-sigma modulator and digital interpolation/filtering for ADC operation, as well as a digital smoothing filter and delta-sigma modulator for DAC operation. The converter supports adjustable sampling rates, making it versatile for various audio applications.

How Many Pins does AK4528VF have and What are the Functions of the Pinout Configuration?

The AK4528VF is housed in a 28-pin SSOP (Shrink Small Outline Package) package. The pinout configuration includes:

  • DOUT1, DOUT2: Digital audio output pins for the ADC.
  • DIN1, DIN2: Digital audio input pins for the DAC.
  • BICK, LRCK: Bit clock and left/right clock pins for audio data synchronization.
  • SDTI, SDTO: Serial data input and output pins for control and configuration.
  • REFP, REFN: Reference voltage input pins.
  • AVDD, DVDD: Analog and digital power supply pins, respectively.

What are the Pros and Cons of AK4528VF?

Pros:

  • High Resolution: Provides 24-bit resolution for professional audio applications.
  • Low Distortion: Achieves low distortion and high signal-to-noise ratio for high-quality audio reproduction.
  • Adjustable Sampling Rates: Supports various sampling rates for flexibility in audio system design.
  • Integrated Functions: Combines both ADC and DAC in a single package, reducing component count in audio systems.
  • Low Power Consumption: Operates with low power, suitable for portable audio devices.

Cons:

  • Complex Interface: Requires careful attention to digital audio interface timing and synchronization.
  • External Components: May require additional external components such as filters or amplifiers for specific audio system requirements.
