ANALOG DEVICES ADAU1787BCBZRL7 CODEC IC, Audio DSPs, 4 x ADC / 2 x DAC, 1.7 V to 1.98 V, WLCSP-42

ADAU1787 is a codec with four inputs and two outputs that incorporates two digital signal processors(DSPs). The path from the analogue input to the DSP core to the analogue 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. Typical application includes 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 and smartphones.
