New Digital Microphone suits Mobile Phones, Digital Still Cameras, and MP3 Players.
Knowles Acoustics has announced its new “Digital” series of SiSonicä SMD microphones - said to be the worlds first “Digital” surface mount microphone and based on Knowles' MEMS microphone technology.
With availability in multiple package sizes, the device is ideally suited for applications where component density is at an absolute premium – such as Mobile Phones, Digital Still Cameras, and MP3 Players.
Compared to the “Analog” SiSonic microphone, the “Digital” SiSonic is a Pulse Density Modulation (PDM) device, has an integrated sleep mode, and is compatible with stereo input applications. This microphone simplifies the design process in multiple portable electronics devices. The design of the Digital SiSonic incorporates the same patented MEMS technology utilized across the expanding SiSonic product range. Therefore, it can be assembled using standard automatic pick-n-place equipment, conforms to lead-free requirements, and is compatible with typical industry Pb-free solder profiles (260°C reflow for 30 seconds maximum).
SiSonic is available with a standard supply voltage range of 1.6 to 2.9V, has maximum current consumption of 500uA, is compatible with high temperature reflow, and is rated to operate up to 100° C.
