EL2386
250MHz Triple Current Feedback Amplifier
with Disable
The EL2386 is a triple current-
feedback operational amplifier which
achieves a -3dB bandwidth of 250MHz
at a gain of +1 while consuming only 3mA of supply current
per amplifier. It will operate with dual supplies ranging from
1.5V to 6V, or from single supplies ranging from +3V to
+12V. The EL2386 also includes a disable/power-down
feature which reduces current consumption to 0mA while
placing the amplifier output in a high impedance state. In
spite of its low supply current, the EL2386 can output 55mA
while swinging to 4V on 5V supplies. These attributes
make the EL2386 an excellent choice for low power and/or
low voltage cable-driver, HDSL, or RGB applications.
For single and dual applications, consider the EL2186/
EL2286. For single, dual, and quad applications without
disable, consider the EL2180, EL2280, or EL2480, all in
industry-standard pinouts. The EL2180 also is available in
the tiny SOT-23 package, which is 28% the size of an SO8
package. For lower power applications where speed is still a
concern, consider the EL2170/EL2176 family which also
comes in similar single, dual, and quad configurations. The
EL2170/EL2176 family provides a -3dB bandwidth of 70MHz
while consuming 1mA of supply current per amplifier.

NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which is compatible with both SnPb and
Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed
the Pb-free requirements of IPC/JEDEC J Std-020B.
