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.
