ADAU1797BCBZRL

ADAU1797BCBZRL is a high-performance audio codec with integrated HiFi 3z and FastDSP cores. It is a low-power, high-performance audio codec that provides three analogue input channels, ten DMIC input channels, two PDM output channels, and one high-efficiency Class-D amplifier output channel. The device features a low-power HiFi 3z audio DSP core and a low-latency FastDSP core. The audio DSP cores paired with high-fidelity audio data converters are ideal for applications like noise cancellation, transparency, personal sound amplification, and voice processing. When operating in low-power mode, the DSP cores are optimized for small form factor applications such as true wireless stereo (TWS) headphones. The application includes true wireless stereo (TWS) ANC headphones, over-ear stereo ANC headphones, VR and AR headsets and wearable devices, hearing assist and PSAP devices, soundbar and smart speaker systems, gaming devices, and tablets.
