For I
CC
> 9mA at any closed loop gain setting, a good starting point for R
F
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:
Evaluation Board
Device Package
Part Number
LMH6732MF SOT-23 LMH730216
LMH6732MA SOIC LMH730227
The supply current adjustment resistor, R
P
, 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.
