AK5373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AK5373ADC/DAC - 特殊用途該產品族中的產品可用于模擬和數字表示的信息轉換，適用于特定用例，或集成了通用數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 AK5373 is a stereo A/D converter with a USB 2.0 interface. The device includes an integrated USB serial interface engine, a USB transceiver, an audio class processing block, endpoints, and a 24-bit stereo audio ADC. An integrated PLL enables the use of multiple sampling frequencies. A microphone amplifier and an integrated programmable gain amplifier are available for processing low-level signals from an analog microphone element. An external EEP-ROM is used to store the descriptor information. The AK5373 is housed in a 48-pin package. It is a low power device, operating from +3.3V, and consuming just 100mW in active mode and less than 100μA in suspend mode.
