Applications Information
Product Description
The EL2170, EL2270, and EL2470 are current-feedback
operational amplifiers that offer a wide -3dB bandwidth of
70MHz and a low supply current of 1mA per amplifier. All of
these products also feature high output current drive. The
EL2170 can output 100mA, while the EL2270 and the
EL2470 can output 55mA per amplifier. The EL2170,
EL2270, and EL2470 work with supply voltages ranging from
a single 3V to ±6V, and they are also capable of swinging to
within 1V of either supply on the input and the output.
Because of their current-feedback topology, the EL2170,
EL2270, and EL2470 do not have the normal gain-bandwidth
product associated with voltage-feedback operational
amplifiers. This allows 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 EL2170, EL2270, and EL2470
the ideal choice for many low-power/high-bandwidth
applications such as portable computing, HDSL, and video
processing.
For applications where board space is extremely critical, the
EL2170 is available in the tiny 5-pin SOT-23 package, which
has a footprint 28% the size of an 8-pin SO. The EL2170,
EL2270, and EL2470 are each also available in industry
standard pinouts in PDIP and SO packages.
For single and dual applications with disable, consider the
EL2176 (8-pin single) and EL2276 (14-pin dual). If higher
speed is required, refer to the EL2180/EL2186 family which
provides singles, duals, triples, and quads with 250MHz of
bandwidth while consuming 3mA of supply current per
amplifier.
Power Supply Bypassing and Printed Circuit
Board Layout
As with any high-frequency device, good printed circuit
board layout is necessary for optimum performance. Ground
plane construction is highly recommended. 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
0.1μF 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). Ground plane
construction should be used, but 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
