Working Principles

The PCM1723E operates by converting analog audio signals into digital data using a high-resolution ADC (Analog-to-Digital Converter). The digital data is then processed and converted back into analog signals using a high-performance DAC (Digital-to-Analog Converter). The on-chip digital filters further enhance the audio signal quality, providing a high-fidelity output.

Detailed Application Field Plans

The PCM1723E is suitable for a wide range of professional audio applications, including:

1. Studio recording and mixing consoles
2. Digital audio workstations (DAWs)
3. Broadcast and production equipment
4. Musical instruments and effects processors
5. Home theater systems
6. Automotive audio systems
