Multi-Channel Audio Hub CODEC for Smartphones
DESCRIPTION
FEATURES
The WM1811G is a highly integrated ultra-low power hi-fi
CODEC designed for smartphones and other portable devices
rich in multimedia features.
An integrated stereo Class D speaker driver and Class W
headphone driver minimize power consumption during audio
playback.
The device requires only two voltage supplies, with all other
internal supply rails generated from integrated LDOs.
Stereo full duplex asynchronous sample rate conversion and
multi-channel digital mixing combined with powerful analogue
mixing allow the device to support a huge range of different
architectures and use cases.
A programmable parametric EQ provides speaker compensation
in the digital playback paths. The dynamic range controller can
be used in record or playback paths for maintaining a constant
signal level, maximizing loudness and protecting speakers
against overloading and clipping.
A smart digital microphone interface provides power regulation,
a low jitter clock output and decimation filters for up to two digital
microphones. Microphone activity detection with interrupt is
available.Low power jack detection is supported via a dedicated
input pin. Impedance sensing and measurement is provided for
external accessory / push-button detection.
Fully differential internal architecture and on-chip RF noise filters
ensure a very high degree of noise immunity. Active ground loop
noise rejection and DC offset correction help prevent pop noise
and suppress ground noise on the headphone outputs.
24-bit 2-channel hi-fi DAC and 2-channel hi-fi ADC
100dB SNR during DAC playback (‘A’ weighted)
