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.  
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 = 560W, driving a load  
of 150W, showing a clean ±600mV signal at the output.  
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:  
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.

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.)  
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.  
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.  
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 40µs. This is a ther-  
mal settling error caused by a power dissipation
