AK4353集成電路（IC）的ADC/DAC-特殊用途規(guī)格書PDF中文資料

AK4353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的AK4353ADC/DAC - 特殊用途該產品族中的產品可用于模擬和數(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 AK4353 is a stereo CMOS D/A Converter and Digital Audio Interface Transmitter. The DAC signal outputs are single-ended and are analog filtered to remove out of band noise. Therefore no external filters are required. The AK4353 can operate at the power supply from 2.7V to 5.5V and the digital I/F can correspond to both TTL and CMOS levels.
