250 MHz Triple Current Feedback Amp w Disable
General Description
The EL2386C is a triple current-feedback operational amplifier
which achieves a
while consuming only 3 mA of supply current per amplifier It
will operate with dual supplies ranging from
from single supplies ranging from
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
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
ing 1 mA of supply current per amplifier
