9mA at any closed loop gain setting, a good
starting point for R
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 for more
information). National Semiconductor suggests the following
evaluation boards as a guide for high frequency layout and
as an aid in device testing and characterization:
Device
Package
Evaluation Board
Part Number
CLC730216
CLC730227
LMH6732MF
LMH6732MA
SOT23-6
SOIC
These evaluation boards are shipped when a device sample
request is placed with National Semiconductor. The supply
current adjustment resistor, R
, in both evaluation boards
should be tied to the appropriate potential to get the desired
supply current. To do so, leave R2 (CLC730216)
[ R5
(CLC730227) ]
uninstalled. Jumper "Dis" connector to V
.
Install R1 (CLC730216)
[ R4 (CLC730227) ]
to set the supply
current.
