The AK5374 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 AK5374 is housed in a 36-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.
