ADNS-2610 Optical Mouse Sensor

Data Sheet

The ADNS-2610 is a new entry level, small form factor optical mouse sensor. It is used to implement a nonmechanical tracking engine for computer mice. Unlike its predecessor, this new optical mouse sensor allows for more compact and affordable optical mice designs.

It 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.

The sensor is housed in an 8-pin staggered dual inline package DIP . It is for use with the HDNS-2100 Lens, HLMP-ED80-XX000, and the HDNS-2200 LED Clip, providing an optical mouse solution that is compact and affordable. There are no moving parts, so precision optical alignment is not required, thereby facilitating high volume assembly.

The output format is a two wire serial port. The current X and Y information are available in registers accessed via the serial port.

Resolution is 400 counts per inch cpi with rates of motion up to 12 inches per second ips .

Theory of Operation

The ADNS-2610 is based on Optical Navigation Technology. It contains an Image Acquisition System IAS , a Digital Signal Processor DSP and a two wire port.

The IAS acquires microscopic surface images via the lens and illumination system provided by the HDNS-2100, HDNS-2200, and HLMP-ED80-XX000. These images are processed by the DSP to determine the direction and distance of motion.

CAUTION It is advisable that normal static precautions should be taken in the handling and assembly of this component to prevent damage and/or degradation which may be induced by ESD.

Overview of Optical Mouse Sensor Assembly

NOTE Pin 1 of optical mouse sensor should be inserted into the reference point of mechanical cutouts.

Figures 3 and 4 are shown with HDNS-2100, HDNS-2200 and HLMP-ED80-XX000.

Avago Technologies provides an IGES file drawing describing the base plate molding features for lens and PCB alignment.

The components shown in Figure 5 interlock as they are mounted onto defined features on the base plate.

The ADNS-2610 sensor is designed for mounting on a through hole PCB, looking down. There is an aperture stop and features on the package that align to the lens.

The HDNS-2100 lens provides optics for the imaging of the surface as well as illumination of the surface at the optimum angle. Features on the lens align it to the sensor, base plate, and clip with the LED. The lens also has a large round flange to provide a long creepage path for any ESD events that occur at the opening of the base plate.

The HDNS-2200 clip holds the LED in relation to the lens. The LED’s leads must be formed first before inserting into the clip. Then, both LED and clip is loaded on the PCB. The clip interlocks the sensor to the lens, and through the lens to the alignment features on the base plate.

The HLMP-ED80-XX000 is recommended for illumination. If used with the bin table as shown in Figure 8 , sufficient illumination can be guaranteed.
