  4. 96dB SNR high performance audio DAC and 90dB SNR ADC.

Recording Function

  1. It can realize MIC recording and AUX recording
  2. The recorded data can be stored in U disk, TF card or SPI FLash, SPI FLash. Support file management, which can realize file index recording, file name recording and other functions.
  3. Access and interact with external devices through the UART interface, the format of the recording file is MP3 format.
  4. Functions such as button recording can be customized. For details, please refer to the program manual.

Recording upload scheme

  • The WT2605X chip supports the recording and uploading function, and the recording data supports connection through UART. The real-time output of the interface is convenient for users to operate the audio data (such as uploading to the server, or applications such as speech recognition).
  • At the same time, the recorded data can also be stored in the local memory, which can be selected as SPI Flash or TF card, U disk as storage.
  • The audio file format supports MP3 or WAV.

Chip Package

  • SOP16、TSSOP24、TSSOP28 、QFN32 (4*4mm)
  • Different recording products can choose different package size chips.

Application

  • Fire safety recording, elevator safety long-term recording, voice recorder, meeting office recording, Fire broadcast system, wireless walkie-talkie recording, etc.
