ADAU1787BCBZRL General Description

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.

Key Features

Programmable FastDSP audio processing engine
- Up to 768 kHz sample rate
- Biquad filters, limiters, volume controls, mixing
28-bit SigmaDSP audio processing core
- Visually programmable using SigmaStudio
- Up to 50 MIPS performance
Low latency, 24-bit ADCs and DACs
- 96 dB SNR (signal through PGA and ADC with A-weighted filter)
- 105 dB combined SNR (signal through DAC and headphone with A-weighted filter)
Serial port f_SYNC frequency from 8 kHz to 768 kHz
5 μs group delay (f_S = 768 kHz) analog in to analog out with FastDSP bypass (zero instructions)
4 single-ended analog inputs, configurable as microphone or line inputs
8 digital microphone inputs
2 analog differential audio outputs, configurable as either line output or headphone driver

Application

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
