For ICC > 9mA at any closed loop gain setting, a good starting point for RF would be the 9mA value stated in

Table 2 above. This value could then be readjusted, if necessary, to achieve the desired response.

PRINTED CIRCUIT LAYOUT & EVALUATION BOARDS

Generally, a good high frequency layout will keep power supply and ground traces away from the inverting input

and output pins. Parasitic capacitances on these nodes to ground will cause frequency response peaking and

possible circuit oscillations (see Application Note OA-15 (SNOA367) for more information).

Use the following evaluation boards as a guide for high frequency layout and as an aid in device testing and

characterization:

The supply current adjustment resistor, RP, in both evaluation boards should be tied to the appropriate potential

to get the desired supply current. To do so, leave R2 (LMH730216) [ R5 (LMH730227) ] uninstalled. Jumper

"Dis" connector to V

−. Install R1 (LMH730216) [ R4 (LMH730227) ] to set the supply current.
