Application Scenarios

The AK4387ET-E2 is an ideal choice for a wide range of audio applications, especially for those that require high resolution and clarity like DVD-Audio. It is also suitable for audio systems that experience excessive clock jitter, thanks to the integration of SCF and CTF filters, which increases performance in such systems.

Comparison

• Multi bit architecture modulator ensures improved THD+N performance and a wide dynamic range.
• Integration of SCF and CTF filters increasing performance for systems with excessive clock jitter.
• 24-bit word length and 192kHz sampling rate that makes it ideal for high-resolution audio systems like DVD-Audio.
• Small space-saving 16pin TSSOP package.

• The AK4387ET-E2 is an older model and may not have the latest features or technology compared to the latest audio chips available today.
