Figure 8. Schematic Diagram for USB, PS/2 mouse application with ADNS-3080
Notes
Caps for pins 15 and 17 MUST have trace lengths LESS than 5 mm to nearest ground pin.
Pins 15 and 17 caps MUST use pin 16 GND.
Pin 9, if used, should not be connected to PCB GND to reduce potential RF emissions.
The 0.1 uF caps must be ceramic.
Caps should have less than 5 nH of self inductance.
Caps should have less than 0.2
ESR.
NC pins should not be connected to any traces.
Surface mount parts are recommended.
Care must be taken when interfacing a 5V microcontroller to the ADNS-3080. Serial port inputs on the sensor should
be connected to open-drain outputs from the microcontroller or use an active drive level shifter. NPD and RESET
should be connected to 5V microcontroller outputs through a resistor divider or other level shifting technique.
VDD3 and GND should have low impedance connections to the power supply.
Capacitors connected to pin 15 and 17 should be connected to pin 16 and then to pin 19.
