DESCRIPTION

· The ADAU1787 is a low-power codec featuring four inputs and two outputs, integrated with two digital signal processors (DSPs). It is optimized for low latency from analog input through DSP core to analog output, making it ideal for noise-cancelling headsets. With minimal additional passive components, it offers a comprehensive headset solution.

FEATURES

· Includes a programmable FastDSP audio processing engine with up to 768 kHz sample rate.
· Features 28-bit SigmaDSP audio processing core, visually programmable via SigmaStudio.
· Supports up to 50 MIPS performance with low latency 24-bit ADCs and DACs.
· Offers 96 dB SNR through PGA and ADC, and 105 dB combined SNR through DAC and headphone.
· Equipped with 4 single-ended analog inputs, 8 digital microphone inputs, and 2 analog differential audio outputs.
· Includes PLL supporting input clock rates from 30 kHz to 27 MHz and full-duplex, 4-channel ASRCs.
· Low power consumption at 11.079 mW for typical stereo ANC settings.
· Features I2C and SPI control interfaces, self-boot from I2C EEPROM, and flexible GPIO.

APPLICATIONS

· Suitable for noise-cancelling handsets, headsets, and headphones.
· Ideal for Bluetooth ANC handsets, headsets, and headphones.
· Applicable in personal navigation devices, digital still and video cameras.
· Used in musical instrument effect processors and multimedia speaker systems.
· Effective in smartphones.
