Typical Performance Characteristics
Applications Information
LAYOUT CONSIDERATIONS
The LH0024 LH0024C like most high speed circuitry is
sensitive to layout and stray capacitance Power supplies
should be by-passed as near the device as is practicable
with at least 0 01
capacitors should also be placed as close to device as pos-
sible
COMPENSATION RECOMMENDATIONS
Compensation schemes recommended in Table 1 work well
under typical conditions However poor layout and long
lead lengths can degrade the performance of the LH0024 or
cause the device to oscillate Slight adjustments in the val-
ues for C1 C2 and C3 may be necessary for a given layout
In particular when operating at a gain of

quire adjustment in order to perfectly cancel the input ca-
pacitance of the device
When operating the LH0024 LH0024C at a gain of
the value of R1 should be at least 1 k
The case of the LH0024 is electrically isolated from the cir-
cuit hence it may be advantageous to drive the case in
order to minimize stray capacitances
HEAT SINKING
The LH0024 LH0024C is specified for operation without the
use of an explicit heat sink However internal power dissi-
pation does cause a significant temperature rise Improved
offset voltage drift can be obtained by limiting the tempera-
ture rise with a clip-on heat sink such as the Thermalloy
