Edinburgh, Scotland Wolfson Microelectronics plc today rolled out an integrated codec with a filterless Class-D stereo speaker driver that is said to consume 10 milliwatts in playback mode.
The WM8960 codec also integrates stereo analog-to-digital (A/D) converters, digital-to-analog (D/A) converters, a headphone driver and an internal phase-locked loop (PLL).
The codec is intended for use in portable electronic devices such as mobile phones with stereo speakers and personal video players that require high-quality audio performance with high efficiency to extend battery life, said Yan Goh, Wolfson's product marketing manager.
The WM8960's Class-D speaker driver delivers up to 1-W continuously, offering 1 percent total harmonic distortion (THD) into 8 ohms, and features synchronous clocking with the D/A converter for low noise and pop and click suppression. The codec also includes a capless headphone driver mode, removing the need for bulky external components, according to Goh.
The highly flexible input configuration of the WM8960 includes a complete stereo single-ended or pseudo-differential microphone interface and up to three stereo analog sources to eliminate external analog switches, Goh said.
The WM8960 is available now in a 5 x 5-mm QFN package and is priced at $2.98 in 10,000-piece quantities. Click here for the WM8960 data sheet.
