ADNS-9800
Laser Gaming Sensor
Description
The ADNS-9800 Laser gaming sensor comprises
of sensor and VCSEL in a single chip-on-board (COB)
package. ADNS-9800 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 il-
lumination system. These images are processed by the
DSP to determine the direction and distance of motion.
The DSP calculates the Δx and Δy relative displacement
values. An external microcontroller reads the Δx and Δy
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.

Assembly Recommendation
1. Insert the COB sensor and all other electrical compo-
nents into the application PCB.
2. This sensor package is only qualified for wave-solder
process.
3. Wave-solder the entire assembly in a no-wash soldering
process utilizing a solder fixture. The solder fixture is
needed to protect the sensor during the solder process.
The fixture should be designed to expose the sensor
leads to solder while shielding the optical aperture
from direct solder contact.
4. Place the lens onto the base plate. Care must be taken
to avoid contamination on the optical surfaces.
5. Remove the protective kapton tapes from the optical
aperture of the sensor and VCSEL respectively. Care
must be taken to keep contaminants from entering the
aperture.
6. Insert the PCB assembly over the lens onto the base
plate. The sensor package should self-align to the lens.
The optical position reference for the PCB is set by the
base plate and lens. The alignment guide post of the
lens locks the lens and integrated molded lead-frame
DIP sensor together. Note that the PCB motion due to
button presses must be minimized to maintain optical
alignment.
7. Optional: The lens can be permanently locked to the
sensor package by melting the lens’ guide posts over
the sensor with heat staking process.
8. Install the mouse top case. There must be a feature in
the top case (or other area) to press down onto the
sensor to ensure the sensor and lenses are interlocked
to the correct vertical height.
