ADNS-2051 Optical Mouse Sensor

Data Sheet

The ADNS-2051 is a low cost optical sensor used to implement a non-mechanical tracking engine for computer mice.

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 a 16-pin staggered dual inline package DIP that is designed for use with the HDNS2100 Lens and HDNS-2200 Clip and HLMP-ED80-XX000 639 nm LED illuminator source . There are no moving parts, and precision optical alignment is not required, facilitating high volume assembly.

The output format is two channel quadrature X and Y direction which emulates encoder photo-transistors. The current X and Y information are also available in registers accessed via a serial port.

Default resolution is as 400 counts per inch cpi , with rates of motion up to 14 inches per second ips .

Resolution can also be programmed to 800 cpi.

The part is programmed via a two wire serial port, through registers.
