Analog Devices Inc. ADAU1861 Low Power Codec

Analog Devices Inc. ADAU1861 Low Power Codec offers three inputs and one output that combines two digital-signal processors (DSPs). The route from the analog input to the DSP core to the analog output is optimized for low latency. The device provides up to 768kHz sample rate and 336kB total memory.

The ADI ADAU1861 is available in a 64-lead lead-frame chip scale package (LFCSP).
