Product Summary

The AK4571VQ USB Interface Audio CODEC incorporates a 16-bit CODEC, PLLs, USB transceiver, SIE (serial interface engine), audio class processing unit, FIFO and other required signals into a single chip. The AK4571VQ can simultaneously transmit and receive audio stream data through USB bus. In addition to this, the single-channel ADC and 2- channel DAC can operate at different sampling rates. The AK4571VQ1 has a programmable gain amplifier for analog input (IPGA). The gain range is from -31dB to +24dB with 1dB steps. In addition to the IPGA, the AK4571VQ also has a fixed +20dB pre-amplifier. Analog input signals can be mixed directly with the D/A signal and sent to the LINEOUT pins of the chip.
