Data Sheet
Description
The ADNS-7700 series are compact, low cost, one chip USB LaserStreamTM mouse sensors designed for implemention of a non-mechanical tracking engine in computer mice.
This ADNS-7700 sensor is a 22-pin integrated molded lead-frame DIP package. It comprises a USB controller and LaserStream navigation sensor with VCSEL integrated within a single package. It is designed to be used with the ADNS-6180-001 trim lens or ADNS-6180-002 wide trim lens to achieve the LaserStream performance featured in this document. These parts provide a complete and compact navigation system with no moving parts and precision optical alignment to facilitate high volume assembly. Avago has pre-calibrated the laser power prior shipment, thus NO laser power calibration is required at manufacturer site, therefore reducing assembly time and associated cost.
The motion output is a selectable 8/12/16-bit USB data reporting format. This device is compliant to USB Revision 2.0 low speed specification. The ADNS-7700 series are designed with on-chip One-Time-Programmable (OTP) memory. This enables device configuration flexibility for the manufacturer to cater for various market segments.
Theory of Operation
The ADNS-7700 is based on Laser-Stream navigation technology that measures changes in position by optically acquiring sequential surface images (per frames) and mathematically determining the direction and magnitude of motion movement.
