Wideband digital hybrid ANC

The DA7413 features our proprietary digital ANC technology that can be configured to work in feedback,

feedforward or a novel hybrid mode. In hybrid mode it delivers best-in-class ambient noise suppression in terms

of both magnitude (up to 40 dB at 200 Hz) and frequency range (over 2.5 kHz).

Key to this performance is a custom DSP that is specifically optimized and used for ANC and enables an input-

to-output latency of just 25µs. Meanwhile a dedicated fast equalization (FEQ) path operating at the digital

microphone (DMIC) clock rate improves cancellation at high frequencies and putting latency down to just 5.2µs.
