Wolfson launches mobile handset specific AudioPlus audio and power management solution

Wolfson announced the WM8400, a multimedia CODEC to deliver audio and mixing capability, long battery life and reduced cost for  multimedia mobile handsets.

WM8400 functions include a high performance multimedia CODEC, on-chip FLL, two DC-DC converters and four LDO regulators, all inside a compact 6x6mm BGA package. Flexible hardware control enables the WM8400 to support the generic power management needs of leading multimedia companion processors. Compared to using separate CODEC and power management chips, which typically require two or more discrete components, the WM8400 can help mobile handset designers to save up to 25 percent on the device bill of materials (BOM) and up to 40 percent on the board footprint.

The WM8400 incorporates a low power audio CODEC, which delivers 98dB SNR performance and supports the signal switching, audio conversion and voice mixing requirements of next-generation mobile phones. Allowing designers to quickly add new features and enable flexible end-user modes such as mobile TV while receiving a voice call. The digital core consumes less power than similar devices and can be as low as 5mW during a voice call.
