FAQs

What is AK5397EQ?

The AK5397EQ is a high-performance 24-bit stereo analog-to-digital converter (ADC) designed by AKM Semiconductor. It is suitable for professional audio recording, high-fidelity audio equipment, and measurement instruments requiring high-resolution signal conversion.

How Does AK5397EQ Work?

The AK5397EQ operates by converting analog audio signals into digital format with 24-bit resolution and high dynamic range. It utilizes a delta-sigma modulation technique combined with oversampling to achieve high linearity and low distortion. The converter provides a range of programmable features such as digital filters and output data formatting for versatile audio processing applications.

How Many Pins does AK5397EQ have and What are the Functions of the Pinout Configuration?

The AK5397EQ is housed in a 28-pin SSOP (Shrink Small Outline Package) package. The pinout configuration includes:

  • AVDD, DVDD: Analog and digital power supply pins, respectively.
  • AGND, DGND: Analog and digital ground pins, respectively.
  • AINL, AINR: Analog input pins for the left and right channels, respectively.
  • LRCK, BICK, MCK, SDTI: Serial interface control pins.
  • SDO: Serial data output pin.
  • MODE, RESET, PDN, FLT, DEMP: Control and configuration pins.

What are the Pros and Cons of AK5397EQ?

Pros:
