ADNS-3530 Datasheet | PixArt

Description Features The ADNS-3530 LED optical mouse sensor is a small form factor (SFF) LED illuminated navigation system. The ADNS-3530 is a low-power optical navigation sensor. It has a new, low-power architecture and automatic power management modes, making it ideal for batteryand power-sensitive applications such as cordless input devices. The ADNS-3530 is capable of high-speed motion detection - up to 20 ips and 8 g. In addition, it has an on-chip oscillator and integrated LED to minimize external ponents. The ADNS-3530, along with the ADNS-3150-001 lens, forms a plete and pact mouse tracking system. There are no moving parts which means high reliability and less maintenance for the end user. In addition, precision optical alignment is not required, facilitating high volume assembly. The sensor is programmed via registers through a fourwire serial port. It is packaged in a 16 I/O surface mountable package. Theory of Operation The ADNS-3530 is 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. - Low power architecture - Small form factor - Surface mount technology (SMT) device - Self-adjusting power-saving modes for longest battery life - High speed motion detection up to 20 ips and 8 g - Self-adjusting frame rate for optimum performance - Motion detect pin output - Internal oscillator - no clock input needed - Selectable 500 and 1000 cpi resolution - Wide operating voltage: 2.7V - 3.6V nominal - Four wire serial port - Minimal number of passive ponents - Integrated chip-on-board LED Applications - Optical mice - Optical trackballs - Integrated input devices - Battery-powered input device The ADNS-3530 contains an Image Acquisition System (IAS), a Digital Signal Processor (DSP), and a four wire serial port. The IAS acquires microscopic surface images via the lens and illumination system. These images are...
