Description of Operation and Application
Information
Product Description
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 1k
Ω load, the EL8100, EL8101
have a -3dB bandwidth of 200MHz. Driving a 150
Ω load, the
bandwidth is about 130MHz while maintaining a 200V/s
slew rate. The EL8100 is available with a power-down pin to
reduce power to 30A typically while the amplifier is
disabled.
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.
The amplifiers have an input common mode voltage range
from 0.15V below the negative supply (VS- pin) to within
1.5V of the positive supply (VS+ pin). If the input signal is
outside the above specified range, it will cause the output
signal to be distorted.
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
Ω, the output
swing is about 4.9V at a 5V supply. For the load resistor
150
Ω, 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
