The ADAU1787 is a codec with four inputs and two outputs that incorporates two digital signal processors (DSPs). The path from the analog input to the DSP core to the analog output is optimized for low latency and is ideal for noise cancelling headsets. With the addition of just a few passive components, the ADAU1787 provides a complete headset solution.
Note that throughout the data sheet, multifunction pins, such as BCLK_0/MP1, are referred to either by the entire pin name or by a single function of the pin, for example, BCLK_0, when only that function is relevant.
Applications
- Noise cancelling handsets, headsets, and headphones
- Bluetooth ANC handsets, headsets, and headphones
- Personal navigation devices
- Digital still and video cameras
- Musical instrument effect processors
- Multimedia speaker systems
- Smartphones
This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
