Taipei, Taiwan Avago Technologies introduced a series of small-form-factor (SFF) optical-mouse sensors with an integrated chip-on-board (COB) LED-illuminated optical navigation system. The ADNB-3532/52 optical sensor bundle with trim lens is a complete mouse-tracking system which can be used with surface mount technology (SMT) processes. This series will enable designers of optical mice applications to use automated manufacturing processes to increase productivity and provide consistent quality in the production of miniature mice for a variety of computer and consumer applications.
The ADNB-3532/52 provides up to 20 inches per second (ips) and 8 g of high-speed motion detection, an on-chip oscillator and integrated LED to minimize the number of external components required for the design. The series operates from 2.7 V to 3.6 V and consists of a low-power architecture and automatic power-management modes, making them suitable for use in battery and power-sensitive applications including compact travel mice for notebook PCs, optical pen mice and optical trackballs.
The ADNB-3532/52 series are based on optical navigation technology which measures changes in position by optically acquiring sequential surface images (frames) and mathematically determining the direction and magnitude of movement. They contain an image acquisition system (IAS), a digital signal processor (DSP), and a four-wire support. The IAS acquires microscopic surface images via the lens and illumination systems. These images are then processed by the DSP and determine the direction and distance of motion.
The ADNB-3532/52 series is designed to provide different mounting options to the mouse printed circuit board (PCB). With dimensions of 12.9 x 9.6 x 3.25-mm, the ADNB-3532 comes with solder pads only at the bottom side of the mouse PCB, which does not require a cut out. The ADNB-3552, which has dimensions of 12.9 x 12.5 x 3.25-mm, has solder pads on both sides of the sensor and can be mounted on either the top with a cut out on the PCB to reduce the overall thickness or on the bottom of the mouse PCB.
Pricing: Begins at $3.00 each in 10,000-piece quantities
