USB I/F A/D Converter  
AK5370  
Features:  
General Description  
n Incorporates USB Audio Controller  
The AK5370 is AD converter for USB audio, especially  
USB microphone . The AK5370 integrates USB serial  
USB Serial Interface Engine  
Audio Class Encoder/Decoder  
2 Endpoints (FIFO)  
interface engine, USB transceiver, audio class decoder,  
endpoints, and high quality AD converter into t he chip.  
As the AK5370 incorporates PLL, it can support several  
sampling frequencies, 8kHz, 11.025kHz, 22.05kHz, 44.1kHz,  
and 48kHz with only one crystal. Moreover, the AK5370  
integrates volume control, and mute function.  
It is possible to make USB microphone with a few external  
components  
USB transceiver  
n 16 bit A/D Converter  
1 channel  
Mute/Volume Control  
AGC pin for external control  
A/D S/N: 84dBA (44.1kHz, Gain = 0dB)  
This device is good for not only business application such  
as conferencing but also games, voice recognition, and  
Karaoke.
