over the entire die junction temperature range of 0°C < T
< 150°C.
Supply Voltage Range
The EL2160C has been designed to operate with supply
voltages from ±2V to ±15V. Optimum bandwidth, slew
rate, and video characteristics are obtained at higher sup-
ply voltages. However, at ±2V supplies, the 3dB
bandwidth at AV = +2 is a respectable 70MHz. The fol-
lowing figure is an oscilloscope plot of the EL2160C at
±2V supplies, AV = +2, RF = RG = 560, driving a load
of 150
, showing a clean ±600mV signal at the output.
If a single supply is desired, values from +4V to +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
EL2160C.
Settling Characteristics
The EL2160C offers superb settling characteristics to
0.1%, typically in the 35ns to 40ns range. There are no
aberrations created from the input stage which often
cause longer settling times in other current feedback
amplifiers. The EL2160C is not slew rate limited, there-
fore any size step up to ±10V gives approximately the
same settling time.
As can be seen from the Long Term Settling Error curve,
for AV = +1, there is approximately a 0.035% residual
which tails away to 0.01% in about 40s. This is a ther-
mal settling error caused by a power dissipation
differential (before and after the voltage step). For AV =
-1, due to the inverting mode configuration, this tail does
not appear since the input stage does not experience the
large voltage change as in the non-inverting mode. With
AV = -1, 0.01% settling time is slightly greater than
100ns.
Power Dissipation
The EL2160C amplifier combines both high speed and
large output current drive capability at a moderate sup-
ply current in very small packages. It is possible to
exceed the maximum junction temperature allowed
under certain supply voltage, temperature, and loading
conditions. To ensure that the EL2160C remains within
its absolute maximum ratings, the following discussion
will help to avoid exceeding the maximum junction
temperature.
The maximum power dissipation allowed in a package is
determined by its thermal resistance and the amount of
temperature rise according to:
The maximum power dissipation actually produced by
an IC is the total quiescent supply current times the total
power supply voltage plus the power in the IC due to the
load, or:
where IS is the supply current. (To be more accurate, the
quiescent supply current flowing in the output driver
transistor should be subtracted from the first term
because, under loading and due to the class AB nature of
the output stage, the output driver current is now
included in the second term.)
In general, an amplifier's AC performance degrades at
higher operating temperature and lower supply current.
Unlike some amplifiers, the EL2160C maintains almost
constant supply current over temperature so that AC per-
formance is not degraded as much over the entire
operating temperature range. Of course, this increase in
performance doesn't come for free. Since the current has
increased, supply voltages must be limited so that maxi-
mum power ratings are not exceeded.
