USB Interface Audio CODEC

The AK4571 is a USB Interface Audio CODEC The AK4571 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 AK4571 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 AK4571 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 AK4571 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. The Analog outputs of the AK4571 CAN be attenuated up to 47dB in 1dB steps. The AK4571 also has an Analog bass boost circuit. Bass Boost response CAN be modified by changing the values of external resistors and capacitors. By AKM Semiconductor, Inc.
