AK5373  
24-bit Stereo ADC with USB Interface  
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.
