The PCM1733U/2K is suitable for various audio applications, including:

1. Consumer Electronics: High-quality audio systems, home theaters, soundbars
2. Professional Audio: Studio monitors, mixing consoles, audio interfaces
3. Automotive: Car audio systems, infotainment systems
4. Telecommunications: VoIP phones, conference systems
5. Industrial: Public address systems, audio equipment for industrial machinery

Alternative Models

For alternative options, consider the following models:

1. PCM1794A: 24-bit, 192 kHz, 8-channel audio DAC
2. PCM5102A: 24-bit, 192 kHz, stereo audio DAC with integrated headphone amplifier
3. PCM1796: 24-bit, 192 kHz, 4-channel audio DAC
