2ch A/D Converter with USB I/F

AK5371

General Description

Features:

The AK5371 is stereo A/D converter with USB I/F. The

AK5371 integrates USB serial interface engine, USB

transceiver, audio class processing unit, endpoints, and high

quality 2 channel AD converter into the chip.

ꢀ USB-IF Certified

ꢀ Incorporates USB Audio Controller

USB Serial Interface Engine

Audio Class Encoder/Decoder

2 Endpoints (FIFO)

As the AK5371 incorporates PLL, it can support several

sampling frequencies, 8kHz, 11.025kHz, 22.05kHz, 44.1kHz,

and 48kHz with only one crystal. Moreover, the AK5371

integrates volume control, and mute function.

USB transceiver

ꢀ 16 bit A/D Converter

2 channels

Not only power consumption at normal operation is very

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

Mute/Volume Control

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

The AK5371 includes 20dB fixed gain pre-amplifier. In

addition to this, as the AK5371 also incorporates IPGA which

can amplify the microphone signal up to +24dB, total gain is

44dB maximum.

ꢀ Low Power Dissipation

Normal Operation: 26mA

Suspend Mode: < 1uA

ꢀ Programmable Gain Amplifier (IPGA)

The AK5371 has EEPROM I/F for customizing Device

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

bit, or 4Kbit Microwire^TMtype EEPROM, the AK5371 can

customize Vendor ID, Product ID in Device Descriptor, and

String Descriptor.

+24dB to –31dB @1dB Step

ꢀ 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
