• Manufacturer Part Number: AK5373
• Description: 24-bit Stereo ADC with USB Interface
• Manufacturer: AKM [Asahi Kasei Microsystems]

■
Register information and descriptor information on EEP-ROM are read by SPI I/F (CSN, SK, EPAO and EPAI) pins. The
data on the I/F consists of Instruction Byte, Address Byte (MSB first, 16bits) and Input Data Byte (MSB first, 8bits). The
AK5373 outputs Instruction Byte and Address Byte on a falling edge of SK and down-loads address data from EPAI. The
next address data is read by sending SK signal continuously. Data reading ends by a rising edge of CSN. SK clock speed
is typically 1.5MHz. The AK5373 reads data from EEP-ROM according to a request signal from the USB host after
releasing a reset.
