FAQs

What is AK7755EN?

The AK7755EN is a highly-integrated digital signal processor (DSP) with a 16-bit A/D converter designed by AKM Semiconductor. It is ideal for applications requiring voice processing, speech recognition, and audio data processing, such as smart speakers, voice-controlled devices, and hands-free automotive systems.

How Does AK7755EN Work?

The AK7755EN works by capturing analog audio signals, converting them to digital data using the integrated 16-bit A/D converter, and processing the digital audio data using the built-in DSP functionality. It features various voice processing algorithms and digital audio filters, making it suitable for real-time audio signal enhancement and recognition applications.

How Many Pins does AK7755EN have and What are the Functions of the Pinout Configuration?

The AK7755EN is housed in a 32-pin QFN (Quad Flat No-leads) package. The pinout configuration includes:

  • DVDD: Digital power supply pin.
  • RESET: Reset input pin.
  • INT: Interrupt output pin.
  • DGND: Digital ground pin.
  • MCLKI, BICKI, LRCKI, SDI: Master clock, bit-clock, left/right clock, and serial data input pins, respectively.
  • SDO, LRCKO, MCKO: Serial data output, left/right clock output, and master clock output pins, respectively.
  • AGND: Analog ground pin.
  • AINL+, AINL-: Analog input pins for the left channel.
  • AINR+, AINR-: Analog input pins for the right channel.

What are the Pros and Cons of AK7755EN?
