General Description
The EL2386C is a triple current-feedback operational amplifier

from single supplies ranging from 3V to 12V. The EL2386C
also includes a disable/power-down feature which reduces cur-
rent consumption to 0 mA while placing the amplifier output in
a high impedance state. In spite of its low supply current, the

EL2386C can output 55 mA while swinging to 4V on 5V
supplies. These attributes make the EL2386C an excellent
choice for low power and/or low voltage cable-driver, HDSL, or
RGB applications.

For Single and Dual applications, consider the EL2186C/
EL2286C. For Single, Dual and Quad applications without dis-
able, consider the EL2180C, EL2280C, or EL2480C, all in indus-
try standard pin outs. The EL2180C 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 EL2170C/EL2176C family which also comes in similar Sin-
gle, Dual and Quad configurations. The EL2170C/EL2176C
# Available in single (EL2186C)
and dual (EL2286C) form
# Non-power down versions
available in single, dual, and quad
(EL2180C, EL2280C, EL2480C)

family provides a 3 dB bandwidth of 70 MHz while consum-
ing 1 mA of supply current per amplifier.
# Lower power EL2170C/EL2176C
family also available
(1 mA/70 MHz) in single, dual
and quad.
