AK5371A

2ch A/D Converter with USB I/F

Features:

General Description

USB-IF Certified

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.

Incorporates USB Audio Controller

USB Serial Interface Engine

Audio Class Encoder/Decoder

2 Endpoints (FIFO)

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.

USB transceiver

16 bit A/D Converter

2 channels

Mute/Volume Control

A/D S/N: 84dBA (44.1kHz, Gain = 0dB)

Not only power consumption at normal operation is very low,

but also the current at suspend mode is less than 1μA.

Low Power Dissipation

Normal Operation: 26mA

Suspend Mode: < 1uA

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.

Programmable Gain Amplifier (IPGA)

+24dB to –31dB @1dB Step

The AK5371A has EEPROM I/F for customizing Device

Descriptor and String Descriptor. By connecting 1K bit, 2K

bit, or 4Kbit Microwire^TMtype EEPROM, the AK5371A can

customize Vendor ID, Product ID in Device Descriptor, and

String Descriptor.

20dB Pre-amplifier

On-chip PLL

5 Sampling Frequencies support

8kHz, 11.025kHz

This device is good for not only business application such as

conferencing but also games, voice recognition, and Karaoke.

22.05kHz, 44.1kHz, 48kHz
