10 / 14 page FAN4174/FAN4274 Rev. 2D 10 www.fairchildsemi.com Layout Considerations General layout and supply bypassing play major roles in high frequency performance. Fairchild has evaluation boards to use as a guide for high frequency layout and as an aid in device test- ing and characterization. Follow the steps below as a basis for high frequency layout: • Include 6.8 µF and 0.01µF ceramic capacitors • Place the 6.8 µF capacitor within 0.75 inches of the power pin • Place the 0.01 µF capacitor within 0.1 inches of the power pin • Remove the ground plane under and around the part, especially near the input and output pins to reduce parasitic capacitance • Minimize all trace lengths to reduce series inductances Refer to the evaluation board layouts shown in Figure 6 for more information. When evaluating only one channel, complete the following on the unused channel: 1. Ground the non-inverting input 2. Short the output to the inverting input Evaluation Board Information The following evaluation boards are available to aid in the test- ing and layout of this device: Evaluation board schematics are shown in Figures 5a and 5b, layouts are shown in Figure 6a through 6d.
