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 1μA.
