Wolfson’s world-leading audio devices selected for LG mobile phones

Both the WM8993 audio hub and the WM9093 low power audio amplifier are specifically designed for portable devices such as mobile phones and currently feature in a range of LG handsets. The WM8993 ultra low power hub audio hub is incorporated into several LG phones including the LG-LB4400 music phone, a collaboration between LG and media player manufacturer, iriver. The WM9093 features in a number of LG phones including the Android-powered LG Optimus GT540 smartphone.

The WM8993 provides an exceptional degree of noise immunity and features ground referenced Class W headphone drivers, which results in a dramatic reduction in playback power consumption, giving over 100 hours of playback time in normal use. It also delivers powerful mixing capabilities which allow the device to support a huge range of audio architectures and use cases, while its active ground loop noise rejection and DC offset correction help prevent pop noise and ground noise from degrading headphone output quality.

The high performance, low power WM9093 packs a range of highly configurable input stages, capless Class G headphone outputs and a mono Class D speaker amplifier with auto gain control into a tiny CSP package with a minimal of external components. The audio amplifier is ideal for feature and smart phones where small PCB area, ultra low power consumption and audio quality are paramount.

Duncan Macadie, Product Line Manager for Audio Hubs at Wolfson Microelectronics, said: “Wolfson is a global leader in delivering world-class audio devices for the consumer electronics market, and we are delighted that LG has chosen to incorporate two of our industry-leading devices into a range of its highly integrated mobile phones and smartphones. Our depth of knowledge, expertise, technology and global support makes Wolfson the perfect partner.”
