Applications Information
Product Description
The EL5160, EL5161, EL5260, EL5261, and EL5360 are low
power, current-feedback operational amplifiers that offer a
wide -3dB bandwidth of 200MHz and a low supply current of
0.75mA per amplifier. The EL5160, EL5161, EL5260,
EL5261, and EL5360 work with supply voltages ranging from
a single 5V to 10V and they are also capable of swinging to
within 1V of either supply on the output. Because of their
current-feedback topology, the EL5160, EL5161, EL5260,
EL5261, and EL5360 do not have the normal gain-
bandwidth product associated with voltage-feedback
operational amplifiers. Instead, their -3dB bandwidth to
remain relatively constant as closed-loop gain is increased.
This combination of high bandwidth and low power, together
with aggressive pricing make the EL5160, EL5161, EL5260,
EL5261, and EL5360 ideal choices for many low-
power/high-bandwidth applications such as portable,
handheld, or battery-powered equipment.

FUNCTION
Power Supply Bypassing and Printed Circuit
Board Layout
As with any high frequency device, good printed circuit
board layout is necessary for optimum performance. Low
impedance ground plane construction is essential. Surface
mount components are recommended, but if leaded
components are used, lead lengths should be as short as
possible. The power supply pins must be well bypassed to
reduce the risk of oscillation. The combination of a 4.7µF
tantalum capacitor in parallel with a 0.01µF capacitor has
been shown to work well when placed at each supply pin.
For good AC performance, parasitic capacitance should be
kept to a minimum, especially at the inverting input. (See the
Capacitance at the Inverting Input section) Even when
ground plane construction is used, it should be removed
from the area near the inverting input to minimize any stray
capacitance at that node. Carbon or Metal-Film resistors are
acceptable with the Metal-Film resistors giving slightly less
peaking and bandwidth because of additional series
inductance. Use of sockets, particularly for the SO package,
should be avoided if possible. Sockets add parasitic
inductance and capacitance which will result in additional
peaking and overshoot.
