ADAU1861BCSZ-RL

ADAU1861 is a codec with three inputs and one output that incorporates two digital-signal processors (DSP). The path from the analogue input to the DSP core to the analogue output is optimized for low latency. Application includes automotive audio systems and digital audio effects processor.

• Programmable FastDSP audio processing engine
• Biquad filters, limiters, volume controls, mixing
• Quad MAC per cycle 24 × 24bit multiplier and 64bit accumulator
• 336KB total memory, 106dB SNR (typ, signal through ADC with A-weighted filter)
• Programmable double precision MAC engine for maximum 24- stage equalizer
• Serial-port sample rates from 8KHz to 768KHz
• 3 differential or single-ended analogue inputs, configurable as microphone or line inputs
• Analog differential audio output, configurable as either line output or headphone driver
• 2 PDM output channels, PLL supporting any input clock rate from 30KHz to 36MHz
• 64 lead LFCSP_SS package, temperature range from -40°C to +105°C
