Working Principles

The UDA1380HN/N2,118 operates based on the principle of digital audio processing. It receives analog audio signals from inputs such as line-in or microphone-in, converts them into digital format using an ADC (Analog-to-Digital Converter), processes the digital audio data, and then converts it back to analog format using a DAC (Digital-to-Analog Converter). The processed audio signals can be outputted through line-out, headphone-out, or speaker-out.

Detailed Application Field Plans

The UDA1380HN/N2,118 is suitable for various audio applications, including but not limited to:

1. Portable audio devices (MP3 players, smartphones, tablets)
2. Home entertainment systems
3. Automotive audio systems
4. Gaming consoles
5. Voice recorders
6. Communication devices (walkie-talkies, intercoms)
