General Description
The AK5371A is stereo A/D converter with USB I/F. The
AK5371A integrates USB serial interface engine, USB
transceiver, audio class processing unit, endpoints, and high
quality 2 channel AD converter into the chip.
As the AK5371A incorporates PLL, it can support several
sampling frequencies, 8kHz, 11.025kHz, 22.05kHz, 44.1kHz,
and 48kHz with only one crystal. Moreover, the AKAK5371A
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 1
μ
A.
The AK5371A includes 20dB fixed gain pre-amplifier. In
addition to this, as the AK5371A also incorporates IPGA
which can amplify the microphone signal up to +24dB, total
gain is 44dB maximum.
The AK5371A has EEPROM I/F for customizing Device
Descriptor and String Descriptor. By connecting 1K bit, 2K
bit, or 4Kbit Microwire
TM
type EEPROM, the AK5371A can
customize Vendor ID, Product ID in Device Descriptor, and
String Descriptor.
This device is good for not only business application such as
conferencing but also games, voice recognition, and Karaoke.
