awinic continuously refines its audio signal chainADCproduct portfolio, officially launchingAW89201QNRhigh-performance dual-channel low-power audioADC. This product targetsAIindustrial and consumer scenarios such as toys, conference systems, smart large screens, smart speakers, robot vacuums, security surveillance, and microphone arrays, providing high-performance front-end audio capture solutions.
Audio terminal application scenarios are diversified, with significant differences in channel requirements. Lightweight devices selecting traditional4channelADCsolutions face issues of performance redundancy and high costs, while high-end devices such as multi-microphone arrays and multi-channel echo retrieval have rigid demands for multi-channel synchronous capture; a single-specification product cannot adapt to all scenario needs. Meanwhile, general-purpose main controllers with built-inADCsuffer from insufficient performance, easily leading to noise and distortion issues, making it difficult to meet high-definition audio capture requirements.
Addressing common pain points in the industry such as poor adaptability, high power consumption, and difficult debugging, awinic has refined its gradedADCproduct portfolio. The newAW89201QNRdual-channelADCcomplements the million-unit shipment4channelADCproducts,comprehensively optimizing power consumption, audio quality performance, platform compatibility, and channel scalability, precisely matching the design needs of industrial and consumer terminals across all levels.
Product Advantages
Low Power Consumption, Listening Without Anxiety
AW89201QNRPossesses excellent power consumption control capabilities;48kHzat sampling rates,3.3Vstatic power consumption is only7.7mAwhen powered by1.8V, and static power consumption is as low as6mAwhen powered by.
On the premise of ensuring high-performance audio capture, it effectively reduces continuous system operating power consumption, minimizes device heating, alleviates battery life pressure for battery-powered products, and meets the needs of portable consumer devices for long-duration sound pickup and industrial equipment for uninterrupted monitoring. Compared to solutions with higher channel counts, the dual-channel specification can also help lightweight devices reduce unnecessary power overhead.
High Dynamic Range, Low Noise, High-Clarity Audio CaptureThe chip101dBachieves both Signal-to-Noise Ratio (SNR) and Dynamic Range (DR) of+, with Total Harmonic Distortion plusTHD+NNoise (-94dB) as low as.AECExcellent noise and distortion specifications can effectively suppress ambient background noise, completely capture faint human voices, and simultaneously handle high-decibel sound sources with ease, avoiding signal clipping distortion. High-quality digital audio signals can significantly reduce the computational pressure on back-end noise reduction,4echo cancellation, and speech recognition algorithms, improving the stability of whole-device audio interaction. Maintaining consistent acoustic performance levels with the
channel products within the series, customers can smoothly migrate algorithms and debugging experience between different channel solutions.I2SFlexible
AW89201QNRConfiguration, Reducing Cross-Platform Adaptation DifficultyI2SSupports free configuration ofI2Sformats, compatible with various non-standardtimings.DSPDefinitions ofI2Svary across different main controllers and
platforms on the market; this feature can significantly reduce software adaptation workload, simplify joint debugging between the chip and the main controller, shorten customer product development cycles, improve solution reusability, and facilitate customers in reusing the same software framework on both dual-channel and quad-channel products.
Product Series Layout and Future PlanningAW89201QNRDual-channelADClaunch,together with the mass-produced million-unit shipment4channel audioADCforms a serializedADCproduct matrix, achieving2channel and4channel specification coverage,meeting diverse customer needs ranging from lightweight dual-path acquisition to multi-channel array pickup.
Looking to the future, awinic will continue to invest heavily in the audio signal chain sector, successively launchingADDAintegrated chips and audio interface conversion chips, gradually extending to supporting system-level reference solutions. This will build a complete audio signal chain product ecosystem spanning analog front-end acquisition, digital-to-analog conversion, and interface interconnection, continuously providing one-stop hardware and solution support for audio terminal manufacturers in industrial and consumer fields, helping customers create clear, stable, and smooth audio interaction and audio monitoring products.
