FN7103.7  
200MHz Rail-to-Rail Amplifiers  
Features  
• 200MHz -3dB bandwidth  
The EL8100 and EL8101 represent single rail-to-rail  
amplifiers with a -3dB bandwidth of 200MHz and slew rate of  
200V/µs. Running off a very low 2mA supply current, the  
EL8100 and EL8101 also feature inputs that go to 0.15V  
• 200V/µs slew rate  
• Low supply current = 2mA  
• Supplies from 3V to 5.0V  
• Rail-to-rail output  
below the V - rail.  
S
The EL8100 includes a fast-acting disable/power-down  
circuit. With a 25ns disable and a 200ns enable, the EL8100  
is ideal for multiplexing applications.  
• Input to 0.15V below V -  
S
• Fast 25ns disable (EL8100 only)  
• Low cost  
The EL8100 and EL8101 are designed for a number of  
general purpose video, communication, instrumentation, and  
industrial applications. The EL8100 is available in 8-pin SO  
and 6-pin SOT-23 packages and the EL8101 is available in a  
5-pin SOT-23 package. All are specified for operation over  
the -40°C to +85°C temperature range.  
• Pb-Free available (RoHS compliant)

Description of Operation and Application  
Information  
Product Description  
from 0.15V below the negative supply (V - pin) to within  
S
1.5V of the positive supply (V + pin). If the input signal is  
S
outside the above specified range, it will cause the output  
signal to be distorted.  
The EL8100, EL8101 are wide bandwidth, single supply, low  
power and rail-to-rail output voltage feedback operational  
amplifiers. Both amplifiers are internally compensated for  
closed loop gain of +1 of greater. Connected in voltage  
follower mode and driving a 1kload, the EL8100, EL8101  
have a -3dB bandwidth of 200MHz. Driving a 150load, the  
bandwidth is about 130MHz while maintaining a 200V/us  
slew rate. The EL8100 is available with a power down pin to  
reduce power to 30µA typically while the amplifier is  
disabled.  
The output of the EL8100, EL8101 can swing rail to rail. As  
the load resistance becomes lower, the ability to drive close  
to each rail is reduced. For the load resistor 1k, the output  
swing is about 4.9V at a 5V supply. For the load resistor  
150, the output swing is about 4.6V.  
Choice of Feedback Resistor and Gain Bandwidth  
Product  
For applications that require a gain of +1, no feedback  
resistor is required. Just short the output pin to the inverting  
input pin. For gains greater than +1, the feedback resistor  
forms a pole with the parasitic capacitance at the inverting  
input. As this pole becomes smaller, the amplifier’s phase  
margin is reduced. This causes ringing in the time domain  
Input, Output and Supply Voltage Range  
The EL8100, EL8101 have been designed to operate with a  
single supply voltage from 3V to 5.0V. Split supplies can also  
be used as long as their total voltage is within 3V to 5.0V.

on time is about 200ns. When disabled, the amplifier’s  
supply current is reduced to 30µA typically, thereby  
effectively eliminating the power consumption. The  
amplifier’s power down can be controlled by standard TTL or  
CMOS signal levels at the ENABLE pin. The applied logic

If the output is shorted indefinitely, the power dissipation  
could easily increase such that the part will be destroyed.  
Maximum reliability is maintained if the output current never  
exceeds ±40mA. This limit is set by the design of the internal  
metal interconnections.

The EL8100, EL8101 have a gain bandwidth product of  
100MHz. For gains 5, its bandwidth can be predicted by the  
following equation:  
Gain × BW = 100MHz  
Video Performance  
Power Dissipation  
For good video performance, an amplifier is required to  
maintain the same output impedance and the same  
frequency response as DC levels are changed at the output.  
This is especially difficult when driving a standard video load  
of 150, because the change in output current with DC level.  
Special circuitry has been incorporated in the  
With the high output drive capability of the EL8100, EL8101,  
it is possible to exceed the 125°C absolute maximum  
junction temperature under certain load current conditions.  
Therefore, it is important to calculate the maximum junction  
temperature for the application to determine if the load  
conditions or package types need to be modified for the  
amplifier to remain in the safe operating area.  
EL8100, EL8101 to reduce the variation of the output  
impedance with the current output. This results in dG and dP  
specifications of 0.03% and 0.05°, while driving 150at a  
gain of 2. Driving high impedance loads would give a similar  
or better dG and dP performance.  
The maximum power dissipation allowed in a package is

Driving Capacitive Loads and Cables  
The EL8100, EL8101 can drive 15pF loads in parallel with  
1kwith less than 5dB of peaking at gain of +1. If less  
peaking is desired in applications, a small series resistor  
(usually between 5to 50) can be placed in series with the  
output to eliminate most peaking. However, this will reduce  
the gain slightly. If the gain setting is greater than 1, the gain

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:  
resistor R can then be chosen to make up for any gain loss  
G
which may be created by the additional series resistor at the  
output.  
For sourcing:  
When used as a cable driver, double termination is always  
recommended for reflection-free performance. For those  
applications, a back-termination series resistor at the  
amplifier’s output will isolate the amplifier from the cable and  
allow extensive capacitive drive. However, other applications  
may have high capacitive loads without a back-termination  
resistor. Again, a small series resistor at the output can help  
to reduce peaking.

As with any high frequency device, a good printed circuit

For good AC performance, parasitic capacitance should be  
kept to a minimum. Use of wire wound resistors should be  
avoided because of their additional series inductance. Use  
of sockets should also be avoided if possible. Sockets add  
parasitic inductance and capacitance that can result in  
compromised performance. Minimizing parasitic capacitance  
at the amplifier’s inverting input pin is very important. The  
feedback resistor should be placed very close to the  
inverting input pin. Strip line design techniques are  
recommended for the signal traces.
