The ADAU1861 is a codec with three inputs and one output 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. APPLICATIONS * Automotive audio systems * Digital audio effects processors * Programmable FastDSP audio processing engine * Up to 768 kHz sample rate * Biquad filters, limiters, volume controls, mixing * Tensilica HiFi 3z DSP core * Quad MAC per cycle: 24 × 24-bit multiplier and 64-bit accumulator * Flexible power operation mode: 24.576 MHz, 49.152 MHz, 73.728 MHz, and 98.304 MHz * 336 kB total memory * JTAG debug and trace * Low latency, 24-bit ADCs, and DAC * 106 dB SNR (signal through ADC with A-weighted filter) * 110 dB combined SNR (signal through DAC and headphone with A-weighted filter) * Programmable double precision MAC engine for maximum 24- stage equalizer * Serial-port sample rates from 8 kHz to 768 kHz * 5 μs group delay (fS = 768 kHz) analog in to analog out with FastDSP bypass (zero instructions) * 3 differential or single-ended analog inputs, configurable as microphone or line inputs * 8 digital microphone inputs * Analog differential audio output, configurable as either line output or headphone driver https://elecena.pl/product/23421105/three-adcs-one-dac-low-power-codec-with-audio-dsps 2023-05-10 https://elecena.pl/product/23421105/three-adcs-one-dac-low-power-codec-with-audio-dsps 2025-01-21
