Instructions for Use:

1. Power Supply Connection:

   • Connect the power supply to VDD and GND pins ensuring the voltage is within the specified range (3.0V to 5.5V).

2. Input Signal Connection:

   • Connect the differential input signals to the IN+ and IN- pins. Ensure the signal does not exceed the differential input range of ±1V.

3. Output Configuration:

   • The output can drive loads up to 70mA. Connect the load to the OUT pin with appropriate decoupling capacitors as needed.

4. Decoupling Capacitors:

   • Place a 0.1μF ceramic capacitor close to the VDD pin to ground to ensure stable operation and reduce noise.

5. Operating Conditions:

   • For optimal performance, operate within the specified temperature range and avoid exceeding the maximum ratings listed in the parameter table.

6. Handling Static Electricity:

   • Handle the AD8109ASTZ with care to prevent damage from static electricity. Use proper ESD precautions.

7. Layout Considerations:

   • Keep signal paths short and direct to minimize parasitic effects. Use ground planes liberally to reduce noise and improve performance.

8. Evaluation:

   • For detailed evaluation, refer to the evaluation board documentation provided by Analog Devices.
