WM1811A w Multi-Channel Audio Hub CODEC for Smartphones DESCRIPTION FEATURES 1 24-bit 2-channel hi-fi DAC and 2-channel hi-fi ADC The WM1811A is a highly integrated ultra-low power hi-fi 100dB SNR during DAC playback (A weighted) CODEC designed for smartphones and other portable devices Smart MIC interface rich in multimedia features. - Power, clocking and data input for up to two digital MICs An integrated stereo Class D speaker driver and Class W - High performance analogue MIC interface headphone driver minimize power consumption during audio - MIC activity detect & interrupt allows processor to sleep playback. - Low power jack detection support - Impedance sensing for accessory / push-button detection The device requires only two voltage supplies, with all other 2W stereo (2 x 2W) Class D speaker driver internal supply rails generated from integrated LDOs. Capless Class W headphone drivers Stereo full duplex asynchronous sample rate conversion and - Integrated charge pump multi-channel digital mixing combined with powerful analogue - 5.3mW total power for DAC playback to headphones mixing allow the device to support a huge range of different 4 Line outputs (single-ended or differential) architectures and use cases. BTL Earpiece driver Digital audio interfaces for multi-processor architecture A programmable parametric EQ provides speaker compensation - Asynchronous stereo duplex sample rate conversion in the digital playback paths. The dynamic range controller can - Powerful mixing and digital loopback functions be used in record or playback paths for maintaining a constant TM ReTune Mobile 5-band, 4-channel parametric EQ signal level, maximizing loudness and protecting speakers Dynamic range controller against overloading and clipping. Dual FLL provides all necessary clocks - Self-clocking modes allow processor to sleep A smart digital microphone interface provides power regulation, - All standard sample rates from 8kHz to 96kHz a low jitter clock output and decimation filters for up to two digital Active noise reduction circuits microphones. Microphone activity detection with interrupt is - DC offset correction removes pops and clicks available.Low power jack detection is supported via a dedicated - Ground loop noise cancellation input pin. Impedance sensing and measurement is provided for Integrated LDO regulators external accessory / push-button detection. 80-ball W-CSP package (4.158 x 3.876 x 0.607mm) Fully differential internal architecture and on-chip RF noise filters ensure a very high degree of noise immunity. Active ground loop APPLICATIONS noise rejection and DC offset correction help prevent pop noise Smartphones and music phones and suppress ground noise on the headphone outputs.
