EL2360C
Triple 130 MHz Current Feedback Amplifier
Applications Information
Contd
Supply Voltage Range and Single Supply
Operation
The EL2360C has been designed to operate with
supply voltages from g2V to g15V Optimum
bandwidth slew rate and video characteristics
are obtained at higher supply voltages However
at g2V supplies the b3 dB bandwidth at AV e
a
2 is a respectable 70 MHz The following figure
is an oscilloscope plot of the EL2360C at g2V
supplies AV ea2 RF e RG e 560X driving a
load of 150
X showing a clean g600 mV signal at
the output
2360 – 11
If a single supply is desired values from a4V to
a
30V can be used as long as the input common
mode range is not exceeded When using a single
supply be sure to either 1) DC bias the inputs at
an appropriate common mode voltage and AC
couple the signal or 2) ensure the driving signal
is within the common mode range of the
EL2360C which is typically 15V from each sup-
ply rail
Settling Characteristics
The EL2360C offers superb settling characteris-
tics to 01% typically in the 35 ns to 40 ns range
There are no aberrations created from the input
stage which often cause longer settling times in
other current feedback amplifiers The EL2360C
is not slew rate limited therefore any size step up
to g10V gives approximately the same settling
time
As can be seen from the Long Term Settling Er-
ror curve for AV ea1 there is approximately a
0035% residual which tails away to 001% in
about 40
ms This is a thermal settling error
caused by a power dissipation differential (before
and after the voltage step) For AV eb1 due to
the inverting mode configuration this tail does
not appear since the input stage does not experi-
ence the large voltage change as in the non-in-
verting mode With AV eb1 001% settling
time is slightly greater than 100 ns
Power Dissipation
The EL2360C amplifier combines both high
speed and large output current capability at a
moderate supply current in very small packages
It is possible to exceed the maximum junction
temperature allowed under certain supply volt-
age temperature and loading conditions To en-
sure that the EL2360C remains within it’s abso-
lute maximum ratings the following discussion
will help to avoid exceeding the maximum junc-
tion temperature
The maximum power dissipation allowed in a
package is determined according to 1
