AK5371集成電路（IC）的ADC/DAC-特殊用途規(guī)格書PDF中文資料

AK5371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AK5371ADC/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(zhuǎn)換，適用于特定用例，或集成了通用數(shù)據(jù)轉(zhuǎn)換器中不常見的其他功能。例如針對超聲或汽車雷達應(yīng)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 AK5371 is stereo A/D converter with USB I/F. The AK5371 integrates USB serial interface engine, USB transceiver, audio class processing unit, endpoints, and high quality 2 channel AD converter into the chip.

As the AK5371 incorporates PLL, it can support several sampling frequencies, 8kHz, 11.025kHz, 22.05kHz, 44.1kHz, and 48kHz with only one crystal. Moreover, the AK5371 integrates volume control, and mute function.

Not only power consumption at normal operation is very low, but also the current at suspend mode is less than 1μA.
