ADNS-9500
Laser Gaming Sensor
DataSheet
Description
The ADNS-9500 Laser
gaming
sensor comprises
of sensor and VCSEL in a single chip-on-board (COB)
package. ADNS-9500 provides enhanced features like pro-
grammable frame rate, programmable resolution, config-
urable sleep and wake up time to suit various PC gamers’
preferences.
The advanced class of VCSEL was engineered by
PixArt
Imaging
to provide a laser diode with a single longi-
tudinal and a single transverse mode.
This Laser
gaming
sensor is in 16-pin integrated
chip-on-board (COB) package. It is designed to be used
with ADNS-6190-002 small form factor (SFF) gaming laser
lens to achieve the optimum performance featured in this
document. These parts provide a complete and compact
navigation system without moving part and laser calibra-
tion process is NOT required in the complete mouse form,
thus facilitating high volume assembly.

Theory of Operation
The sensor is based on Laser technology, which
measures changes in position by optically acquiring
sequential surface images (frames) and mathematically
determining the direction and magnitude of movement.
It 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 processed by the
DSP to determine the direction and distance of motion.
The DSP calculates the
x
and
y
relative displacement
values. An external microcontroller reads the
x
and
y
information from the sensor serial port. The microcon-
troller then translates the data into PS2, USB, or RF signals
before sending them to the host PC or game console.
Applications
Corded and cordless gaming laser mice
Optical trackballs
Motion input devices
