The EL2386C is a triple current-feedback operational amplifier
which achieves a
b
3 dB bandwidth of 250 MHz at a gain of
a
1
while consuming only 3 mA of supply current per amplifier It
will operate with dual supplies ranging from
g
1 5V to
g
6V or
from single supplies ranging from
a
3V to
a
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
g
4V on
g
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
family provides a
b
3 dB bandwidth of 70 MHz while consum-
ing 1 mA of supply current per amplifier
