AKM AK4951AEN is a cost-effective stereo CODEC designed to provide high-quality performance and enhanced musical fidelity while also meeting strict power-consumption requirements. This device is well-suited for high-resolution audio applications and is capable of sampling rates up to 32-kHz. It incorporates advanced digital signal processing (DSP) techniques, such as a segmentalized noise gate, that effectively suppress digital noise in real-time applications. It also provides an acoustic echo canceller to improve the user experience when using hands-free communication systems. In terms of application field, the AKM AK4951AEN is widely adopted in various audio devices, multimedia systems, speakers, microphones, digital-audio amplifiers and portable devices (headset, etc).The device is available in a tiny 6.6×6.6mm² QFN-28 package and offers improved thermal performance and miniaturization of audio systems. The AKM AK4951AEN is a two-channel CODEC, which features a single-bit Σ-Δ analog-to-digital converter (ADC) and a 24-bit, oversampling Σ-Δ digital-to-analog converter (DAC) for high-fidelity signal conversion. The signal links are connected through a stereo headphone output, stereo line input and microphone input, allowing up to two audio channels per device. The internal gain can also be set to support a wide dynamic range by using the serial peripheral interface (SPI). Additionally, the dedicated BTL driver provides adequate output power with a small number of external components. In terms of working principle, the AKM AK4951AEN converts both digital audio out of computers and audio devices, as well as analog audio, into digital format to efficiently process sound. The built-in audio signal processor allows high-quality signal conversion and the high-precision automatic gain control (AGC) feature helps to preserve the voice intensity levels during phone calls. The stereo headphone output delivers a 24-bit/48kHz audio stream for users to enjoy high-quality audio playback from their audio devices with minimal power consumption. This device also supports direct digital synthesis (DDS) which helps to avoid static noise distortion and allows for higher dynamic range. Finally, the power management architecture allows for continuous and energy-efficient playing of music for long periods.Overall, the AKM AK4951AEN is well-suited for applications in a variety of portable audio products. With its onboard audio signal processor and built-in automatic gain control, users can enjoy both improved audio quality as well as low power consumption. The available support for direct digital synthesis and its ability to process digital and analog audio help to make the AKM AK4951AEN an efficient and reliable stereo CODEC for a variety of applications.
