ADNS-9800 Laser Gaming Sensor Data Sheet Description Features 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 programmable frame rate, programmable resolution, configurable sleep and wake up time to suit various PC gamers’ preferences. • Small form factor chip-on-board package The advanced class of VCSEL was engineered by PixArt Imaging to provide a laser diode with a single longitudinal 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 calibration process is NOT required in the complete mouse form, thus facilitating high volume assembly. • Dual power supply selections, 3 V or 5 V • VDDIO range: 1.65 – 3.3 V • 16-bits motion data registers • High speed motion detection up to 150 ips and acceleration up to 30 g • Advanced technology 832-865 nm wavelength VCSEL • Single mode lasing • No laser power calibration needed • Compliance to IEC/EN 60825-1 Eye Safety – Class 1 laser power output level – On-chip laser fault detect circuitry • Self-adjusting frame rate for optimum performance • Motion detect pin output • Internal oscillator – no external clock input needed 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 Δx and Δy relative displacement values. An external microcontroller reads the Δx and Δy information from the sensor serial port. The microcontroller then translates the data into PS2, USB, or RF signals before sending them to the host PC or game console. • Enhanced Programmability – Frame rate up to 12,000 fps – 1 to 5 mm lift detection – Resolution up to 8200 cpi with ~50 cpi step – X and Y axes independent resolution setting – Register enabled Rest Modes – Sleep and wake up times Applications • Corded and cordless gaming laser mice • Optical trackballs • Motion input devices CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component to prevent damage and/or degradation which may be induced by ESD.

Recommended PCB mechanical cutouts and spacing Assembly Recommendation 1. Insert the COB sensor and all other electrical components 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.
