Design Notes
The AD8351ARMZ-REEL7 operates from a single 5V supply. Ensure the supply is clean and well-regulated, with a 0.1Β΅F ceramic capacitor placed close to the VCC pin and a 10Β΅F bulk capacitor nearby. This minimizes power supply noise that could degrade the amplifier's noise and distortion performance.
For optimal high-frequency performance, place the gain-setting resistor as close to the RG pin as possible to minimize parasitic inductance. Use controlled impedance traces for the differential inputs and outputs, and keep the ground plane continuous under the device. This reduces signal reflections and maintains the amplifier's bandwidth and linearity.
Do not exceed the absolute maximum supply voltage of 5.5V, as this can damage the device. Also, ensure the gain resistor is within the recommended range to avoid instability. When driving capacitive loads, such as ADC inputs, consider adding a series resistor to isolate the amplifier from the load and prevent oscillation.
