ADAU1961WBCPZ-R7

The ADAU1961WBCPZ-R7 is an audio codec integrated circuit developed by Analog Devices Inc., a leading provider of analog and digital signal processing solutions, in collaboration with Maxim Integrated. This IC combines analog-to-digital conversion (ADC) and digital-to-analog conversion (DAC) functionalities, along with advanced audio processing features, to deliver high-quality audio performance in various applications.

Key Features:

• Analog-to-Digital Conversion (ADC): The ADAU1961WBCPZ-R7 integrates high-resolution ADCs, allowing analog audio signals to be converted into digital format with exceptional accuracy and fidelity. This is essential for capturing audio from external sources such as microphones, line inputs, or sensors.

• Digital-to-Analog Conversion (DAC): It also features high-performance DACs, enabling digital audio signals to be converted back into analog format with precise reconstruction of the original waveform. This facilitates playback of audio through headphones, speakers, or other output devices.

• Multi-Channel Audio Support: The codec supports multiple audio channels, enabling stereo, multi-channel surround sound, or mono configurations to suit various audio playback or recording requirements.

• Sample Rate Conversion (SRC): The ADAU1961WBCPZ-R7 may incorporate sample rate conversion functionality, allowing audio signals to be converted between different sample rates, ensuring compatibility with various audio sources and destinations.

• Digital Signal Processing (DSP): Analog Devices is known for its expertise in digital signal processing (DSP) technology. The codec may feature built-in DSP capabilities for real-time audio processing tasks such as equalization, filtering, mixing, and dynamic range compression.

• Integrated Microphone Preamps: It may include integrated microphone preamplifiers with programmable gain settings, enabling direct connection of microphones and simplifying the design of microphone input circuits.

• I2S and SPI Interfaces: The codec likely interfaces with external microcontrollers or digital signal processors (DSPs) using industry-standard communication interfaces such as I2S (Inter-IC Sound) and SPI (Serial Peripheral Interface), allowing for seamless integration into digital audio systems.

• Low Power Consumption: Analog Devices and Maxim Integrated prioritize low power consumption in their IC designs, making the ADAU1961WBCPZ-R7 suitable for battery-powered portable devices and energy-efficient audio applications.

• Compact Package: The IC is packaged in a compact and space-efficient form factor, such as a lead-free, RoHS-compliant LFCSP (Lead Frame Chip Scale Package) or QFN (Quad Flat No-Lead) package, facilitating easy PCB layout and assembly.

Applications:

• Portable Audio Devices: Used in smartphones, tablets, portable media players, and handheld recorders for high-quality audio playback and recording capabilities.

• Professional Audio Equipment: Integrated into professional audio interfaces, mixing consoles, and studio recording equipment for studio-quality audio production, mixing, and mastering.
