The WAU8812 is a high-performance,cost-effective mono audio CODEC designed specifically for VoIPphones, hands-free kits and general-purpose speakerphones. Itdelivers exceptional flexibility in performance and optimization ofpower consumption, while providing designers with development andtest tools that can dramatically accelerate time to market.



The WAU8812 features a robust, high-fidelity, 24-bit signalarchitecture delivering 93dB digital-to-analog converter (DAC)signal to noise ratio (SNR) and 91dB analog-to-digital converter(ADC) SNR at audio sampling rates from 8KHz to 48KHz. The deviceoperates at an industry-leading 6uA standby current, which greatlyreduces power consumption and extends battery life in hand-heldapplications.

The CODEC reduces external component requirements by integrating aspeaker driver, headset driver and a configurable low-noise,microphone-biasing circuit. It also includes two microphone inputs,a single auxiliary input and two dedicated analog outputs. Thedigital filter block includes a soft mute and a notch filter toreduce out-of-band noise. The WAU8812's speaker and mono outputshave a dedicated supply of 2.5 to 5.5 volts, which enable increasedoutput power as required. Industry-standard digital interfacesinclude I2S and PCM with programmable time slot assignments. Inaddition, the CODEC is AEC-Q100-compliant for automotiveapplications.

The WAU8812's powerful development platform and simple graphicaluser interface development tools enable designers to efficientlygenerate new designs, giving them interactive programmability andpredefined configuration paths for test and development.
