Annwa launched the optical mouse sensor and built-in LED and adjust the lens

Avago Technologies (Annwa) recently announced the launch of COB package built-in LED lighting optical guidance system, small size (SFF, Small Form Factor) optical mouse sensor series, equipped with than the traditional guidance kit (ADNB-3042) 97% small compact package, Avago ADNB-3532/52 integrated optical sensor suite collocation to adjust the lens to form a complete mouse tracking system, is also the first to adopt the surface mount technology to produce optical mouse kit. The new series of optical mouse sensor Avago launched optical mouse can help application designers use automatic production process to enhance productivity and quality of output when the mass production is consistent for the use of a wide range of computer wireless input devices and consumer applications.

ADNB-3532/52 is equipped with up to 20 inches per second (IPS) and 8g high-speed mobile detection capabilities, while the chip built-in oscillator circuit and integrated LED can be designed to reduce the number of external devices to the minimum. Avago ADNB-3532/52 series includes a low power architecture and automatic power management mode, which makes them very suitable for use in a variety of applications in battery powered or rather focus on power consumption, such as a variety of small travel notebook computer with a mouse, light pen mouse, optical trackball and consumer applications used in other wireless input device.

Avago ADNB-3532/52 series uses optical guidance technology, optical mode continues reading continuous surface image, and through mathematical calculations to determine the direction and magnitude of the move, the ADNB-3532/52 includes an image capture system (IAS Image, Acquisition System), a digital signal processor (DSP Digital, Signal Processor) and a four support line type connection, IAS lens and lighting system by capturing miniature image surface, these images are then processed by DSP to determine the direction and distance of moving, this kind of optical mouse suite with no moving parts, in addition to help to improve the reliability of terminal users givers don't need maintenance.

The ADNB-3532/52 series provides different mounting mouse printed circuit board in the design, the size is 12.9mm * 9.6mm * 3.25mm high Avago wide, ADNB-3532/52 only provides the welding point when the mouse is at the bottom of the circuit board, without cutting action, ADNB-3552 size is 12.9mm * 12.5mm * 3.25mm long wide high. In the sensor on both ends of the welding point, it is possible to reduce the overall thickness of cutting through the above arrangement in the circuit board, or arranged in the circuit board below the mouse.
