Description

The AK5374EN is a stereo A/D converter with a USB 2.0 interface. The device includes an integrated USB serial interface engine, a USB transceiver, an audio class processing block, endpoints, and a 24-bit stereo audio ADC. An integrated PLL enables the use of multiple sampling frequencies. A microphone amplifier and an integrated programmable gain amplifier are available for processing low-level signals from an analog microphone element. An external EEP-ROM is used to store the descriptor information. The AK5374EN is housed in a 36-pin package. It is a low power device, operating from +3.3V, and consuming just 100mW in active mode and less than 100μA in suspend mode.
