250MHz Triple Current Feedback Amplifier
with Disable
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.
Ordering Information
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.
