ADAU1961WBCPZ-R7 Interface - CODECs
The ADAU1961WBCPZ-R7 is an interface CODEC (coder-decoder) is a device that allows audio signals to be processed and transmitted digitally. It performs A/D conversion, low latency AEC, and digital audio processing while also providing a straightforward interface to a digital audio controller. This makes it ideal for applications such as cell phones, voice-over-IP, and multimedia devices.The ADAU1961WBCPZ-R7 is a four-channel CODEC that is designed to provide low noise and low distortion performance, low power consumption, and ease of use for embedded audio applications. It is designed for use with 8-, 16-, and 32-bit microcontrollers, and it supports popular audio formats including PCM, ADPCM, and IMA ADPCM.The device has two parallel digital audio interfaces, one I2S, and one PDM, allowing it to cover a wide range of embedded audio applications. It supports stereo or mono input/output, so it can be used for both microphone and speaker applications, and it also supports multiple sample rates, from 8 kHz up to 48 kHz. Additionally, it has an internal PLL for clock synchronization, further simplifying its use.The ADAU1961WBCPZ-R7 has an integrated audio signal processor (ASP), which allows it to perform high-performance signal processing such as noise suppression, echo cancellation, gain and volume control, loudness correction, and resonant filter processing. This makes it an ideal choice for applications that require high-fidelity audio processing.The device also has an integrated microphone interface, which allows it to accept two digital audio inputs. It is designed to support two different microphone types, differential and single-ended, and it supports various sampling rates, from 8 kHz up to 48 kHz. This makes it ideal for applications where several microphones are used, such as in a conference call or teleconferencing.Finally, the ADAU1961WBCPZ-R7 features an integrated low-power amplifier, allowing it to drive a speaker directly. It can provide up to 9 W of power, allowing it to be used as a loudspeaker in portable applications. The amplifier also supports gain and volume control, allowing it to be used as a stereo or mono speaker, as well as multiple loudspeaker configurations.In summary, the ADAU1961WBCPZ-R7 is a versatile, low power, and low-noise interface CODEC that can be used for a wide range of embedded audio applications. It supports two digital microphone interfaces, stereo/mono input/output, and multiple sample rates, and it also has an integrated audio signal processor and low-power amplifier. All of these features make it an ideal choice for applications where high-quality audio processing is needed.
