The AK4647VQ integrated CODEC is a CMOS Audio Application Specific product intended for portable applications. The CODEC integrates a stereo line input, a stereo headphone amplifier, a microphone amplifier, and a stereo line output with low noise, low distortion level and low current consumption. This device uses C-MOS technology and includes an 18-bit Delta-Sigma A/D, a 16-bit Delta-Sigma A/D and DAC, GPIO and I2C Bus control. The AK4647VQ was designed to meet the demands of mobile products such as phones, PDAs, and portable media players.

The application area of the AK4647VQ CODEC is mainly portable devices. It is ideal for applications such as digital video recorders, VoIP devices, video game consoles, digital TV receiver and set-top boxes, digital photography cameras and camcorders, digital picture frames, etc. It is suitable for applications that require high quality sound but also demand low power consumption.

The AK4647VQ CODEC has two main components: A/D and D/A. The A/D converts analog signals from the line input or microphone input to digital signals, while the D/A converts digital signals to analog signals for the playback of sounds through an external amplifier and loudspeaker. The CODEC also includes an I2C Bus control. This allows setting of the various modes and parameters, such as gain and signal processing.

The AK4647VQ CODEC\'s working principle is based on delta-sigma modulators. The A/D delta-sigma modulator receives analog input and converts it into a digital signal by carrying out oversampling and noise shaping. The resulting signal is a stream of numbers that is sent to the DAC. The DAC then reconstructs the analog signal from the digital values. To achieve a good signal to noise ratio, the AK4647VQ CODEC employs 34-bit delta-sigma modulators and oversampling data bandwidth.

The AK4647VQ CODEC also features on-chip memory, allowing the user to store settings. This memory configuration can be used to store the gain settings of the microphone and the line input, the Signal to Noise Ratio (SNR) settings, the distortion settings and other parameters. Moreover, the user can also adjust these parameters directly via the I2C Bus control.

The AK4647VQ CODEC is particularly recommended for use in applications that require low current consumption and high quality sound performance. It operates within a wide range of temperatures, from -40°C to +85°C, allowing it to be used in harsh environments. The CODEC is designed for durability and features power-saving features for extended battery life.

In conclusion, the AK4647VQ CODEC is a CMOS Audio Application Specific product intended for portable applications. The device uses C-MOS technology and includes an 18-bit Delta-Sigma A/D, a 16-bit Delta-Sigma A/D, DAC, GPIO and I2C Bus control. The application area of the AK4647VQ CODEC is mainly portable devices such as digital video recorders, VoIP devices, video game consoles and other portable devices. The working principle is based on delta-sigma modulators and employs 34-bit delta-sigma modulators and oversampling data bandwidth. The CODEC is particularly recommended for use in applications that require low current consumption and high quality sound performance. Its on-chip memory and I2C bus control make it a great choice for mobile applications.
