The WM8958 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/AB 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 multiband compressor and programmable parametric EQ
provide volume maximisation and 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 four
digital microphones. A MIC activity detect with interrupt is
available.
Active ground loop noise rejection and DC offset correction help
prevent pop noise and suppress ground noise on the headphone outputs.
