The WM2002 features a unique feedforward noise cancellation technology that delivers best-in-class digital ANC performance with up to 30dB of peak active ambient noise cancellation. With acoustics, the WM2002 actively eliminates noise up to 3.5KhZ and maintains exceptional audio quality to ensure that users listen to music or answer calls in a variety of noisy environments. It allows manufacturers to significantly reduce development costs and time on the market and on the production line; this solution requires less printed circuit board (PCB) footprint, which allows designers to create more flexibility Addictive design.
Designed for a variety of embedded applications, the WM2002 can be integrated into a stand-alone earmuff or earbuds/headset that supports analog playback and analog or digital microphone inputs for various noise monitoring microphones. The perfect companion for analog and digital silicon microelectromechanical systems (MEMS) microphones.
The WM2002 provides built-in power management consisting of a DC-DC converter, a charge pump, and multiple low dropout linear (LDO) regulators. The entire device can pass a single AAA battery, two Powered by an AAA battery unit or an external regulated power supply, it offers manufacturers and brand customers unparalleled flexibility. The device can be configured with programmable setup records stored in a built-in non-volatile memory, while configurations stored in one-time programmable (OTP) memory can be automatically enabled at startup.
Wolfson Carey, ANC Business Development Manager, Wolfson, said: “Ou Sheng leads the industry by continuously providing world-class ANC solutions for the consumer electronics market. WM2002 will provide Wolfson Innovation by providing best-in-class digital ANC for headsets and headsets. The myZoneTM technology takes it to the next level while maintaining the integrity of the playback audio quality. This is a true HD audio solution for next-generation noise cancellation products that will help our customers around the world Headphones and headsets with noise cancellation for the mainstream market become reality."
