DA7413中文资料Stereo Codec with Wideband Digital Hybrid Active Noise Cancellation数据手册Renesas规格书

描述 Description

Renesas' DA741x family is a high-performance, ultra-low power Hi-Fi codec with hybrid active noise cancellation (ANC) for hearables, and USB-C™ and Bluetooth® headphone, headset, and hearable applications.

With high-performance playback and record paths, the DA741x family is designed for high dynamic range and minimum latency. Two integrated, individually operatable, digital signal processors are provided. The first, running at 192kHz, is dedicated to noise cancellation applications while the second, running at 48kHz or 192kHz, can perform music and voice processing such as equalization, limiting, mixing, beamforming, and gain control. A dedicated fast equalization (FEQ) path, operating at the digital microphone (DMIC) clock rate, delivers improved high-frequency noise cancellation with ultra-low latency. The device supports four ADCs which enables the use of up to four analog microphones (AMIC) or 6 digital microphones (DMIC).The DA741x is a family of high-performance, ultra-low-power, Hi-Fi codecs for USB-C and Bluetooth headphone (HP), headset, or hearable applications. The family consists of two devices. The DA7414 supports stereo output and the DA7413 supports mono output. Both devices share the same driver and are compatible with each other.
