Audio Special Purpose: ADAU71067Z-CS Application Field and Working Principle

ADAU71067Z-CS is a special purpose audio chip developed by Analog Devices Inc. It is used in audio applications such as industrial, military and automotive, and is designed to meet the stringent requirements of these applications.

The ADAU71067Z-CS is a single-chip audio codec that is integrated with advanced features such as a 20-bit ADC, 16-bit DAC, and a 1.8V low power supply. It is capable of handling a wide range of audio inputs, from line-level (mic in) to audio program streams, and can output audio program streams directly to speakers or multiplex outputs. It also has a built-in sigma-delta modulation core and a variety of control bus interfaces. For example, it has support for I2C and SPI.

The ADAU71067Z-CS audio chip works by first converting incoming analog signals into digital signals. This is achieved through the onboard analog-to-digital converter which can accommodate up to 20-bit audio inputs. Once the analog signals are converted to digital signals, the digital signals are converted back to analog signals for output. This is achieved through the onboard digital-to-analog converter which can produce up to 16-bit audio output. The chip can also support audio processing algorithms for advanced audio processing.

The ADAU71067Z-CS audio chip also supports advanced features such as multi-channel audio processing, environmental noise cancellation, and dynamic range expansion. The multi-channel audio processing allows the chip to process two or more channels of audio signals simultaneously, while the environmental noise cancellation helps to reduce external noise in the audio signal. The dynamic range expansion allows the chip to expand the range of audible frequencies, allowing for better sound reproduction.

The ADAU71067Z-CS audio chip also has an array of control bus interfaces, allowing it to communicate with other devices and processors on the system. For example, it can be connected to an I2C or SPI bus and used to communicate with other devices on the system. This allows the chip to be used for complex audio processing tasks, such as multi-channel mixing and digital signal processing.

The ADAU71067Z-CS is a powerful and versatile audio chip, offering a wide range of features for applications such as industrial, military and automotive. It\'s ability to handle a variety of audio inputs, its range of advanced features, and its control bus interfaces make it an ideal choice for audio applications.
