ADNS-7700
One chip USB LaserStream™ Mouse Sensors
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 as-
sembly. 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 re-
porting 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 tech-
nology that measures changes in position by optically ac-
quiring sequential surface images (per frames) and math-
ematically determining the direction and magnitude of
motion movement.
It contains an Image Acquisition System (IAS), a Digital
Signal Processor (DSP) and USB stream output. The IAS
acquires microscopic surface images via the lens. These
images are processed by the DSP to determine the direc-
tion and distance of motion. The DSP generates the x
and y relative displacement values which are converted
to USB motion data.

Comments:
1. Stress greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are the stress ratings only
and functional operation of the device at these or any other condition beyond those indicated for extended period of time may affect device
reliability.
2. The inherent design of this component causes it to be sensitive to electrostatic discharge. The ESD threshold is listed above. To prevent
ESD-induced damage, take adequate ESD precautions when handling this product.
