AK4393屬于集成電路（IC）的ADC/DAC-特殊用途。由旭化成微電子株式會社制造生產(chǎn)的AK4393ADC/DAC - 特殊用途該產(chǎn)品族中的產(chǎn)品可用于模擬和數(shù)字表示的信息轉換，適用于特定用例，或集成了通用數(shù)據(jù)轉換器中不常見的其他功能。例如針對超聲或汽車雷達應用集成了低噪聲放大器和可變增益級的器件、注重音頻和視頻的產(chǎn)品、在段碼式顯示器上集成顯示測量值功能的器件、集成輸入輸出電氣隔離的器件等。

GENERAL DESCRIPTION

The AK4393 is a high performance stereo DAC for the 96kHz sampling mode ofDAT, DVD including a 24bit digital filter. The AK4393 introducesthe advanced multi-bit system for ΔΣmodulator. This new architecture achieves the widerdynamic range, while keeping muchthe same superior distortion characteristics as conventional Single-Bit way. In the AK4393, the analog outputs are filtered in the analog domain by switched-capacitor filter (SCF) with high tolerance to clock jitter. The analog outputs are full differential output, so the device is suitable for hi-end applications. The operating voltages support analog 5V and digital 3.3V, so it is easy to I/F with 3.3V logic IC.
