AK4495SEQ数据手册集成电路（IC）的ADC/DAC-特殊用途规格书PDF

描述 Description

The AK4495SEQ is a new generation of premium 32-bit DAC, with 2-channels of AKM’s VELVET SOUND architecture that has been widely adopted by well-established high-end audio companies. This technology realizes fine sound details with its low-distortion architecture in addition to 32-bit resolution digital filter processing. By using AKM’s circuit design techniques and pattern layout knowledge, pin configurations and internal layout that provides best sound quality have been adopted for musical performance improvement. The digital input supports up to 768 kHz PCM and 5.6 MHz DSD (Direct Stream Digital), suitable for high-resolution audio source playback. Five digital filters are integrated into the DAC realizing simple and flexible sound, making it ideal for a wide range of applications. The AK4495SEQ is ideal for systems such as Network Audio Players focusing sound quality, SACD players and high-end audio systems supporting high resolution sound source.
