AK4396VF

ADCs/DACs - Special Purpose Overview

The AK4396VF is a high-performance stereo digital-to-analog converter (DAC) designed for 192kHz sampling modes, including DVD-Audio and SACD applications. It utilizes AKM’s multi-bit architecture to deliver wide dynamic range and improved THD+N performance. The device features full differential switched-capacitor filter (SCF) outputs, eliminating the need for external AC coupling capacitors. Key electrical parameters include a dynamic range and signal-to-noise ratio of 120dB, total harmonic distortion plus noise of -100dB, and support for sampling rates from 30kHz to 216kHz. It accepts 192kHz PCM data and 1-bit DSD data.

ADCs/DACs - Special Purpose Feature Summary

• 128x Oversampling with 24-bit 8x Digital Filter offering ±0.005dB ripple and 75dB attenuation
• Full differential SCF outputs for enhanced jitter tolerance and simplified system design
• Support for DSD data input alongside standard PCM formats
• Digital attenuator with linear 256 steps and soft mute functionality

ADCs/DACs - Special Purpose Applications

• DVD-Audio players
• SACD players
• High-end audio systems requiring 192kHz/24-bit resolution

ADCs/DACs - Special Purpose Part Context

The AK4396VF belongs to the AK439x series of premium DACs from Asahi Kasei Microsystems. It is pin-compatible with the AK4393, AK4394, and AK4395 models, allowing for functional compatibility while offering lower power dissipation compared to some predecessors in the family.

ADCs/DACs - Special Purpose Replacement Considerations

The AK4396VF is pin-compatible with the AK4393, AK4394, and AK4395. Designers should verify that the specific performance requirements of the application align with the AK4396's specifications, particularly regarding the 24-bit filter characteristics and power supply constraints.
