General Description
The EL2186CEL2286C are singledual current-feedback oper-
ational amplifiers which achieve a b3 dB bandwidth of
250 MHz at a gain of a1 while consuming only 3 mA of supply
current per amplifier They will operate with dual supplies
ranging from g15V to g6V or from single supplies ranging
from a3V to a12V The EL2186CEL2286C also include a dis-
ablepower-down feature which reduces current consumption to
0 mA while placing the amplifier output in a high impedance
state In spite of its low supply current the EL2286C can out-
put 55 mA while swinging to g4V on g5V supplies The
EL2186C can output 100 mA with similar output swings These
attributes make the EL2186CEL2286C excellent choices for
low power andor low voltage cable-driver HDSL or RGB ap-
plications
For Single Dual and Quad applications without disable consid-
er the EL2180C (8-Pin Single)
EL2280C (8-Pin Dual) or
EL2480C (14-Pin Quad) For lower power applications where
speed is still a concern consider the EL2170CEl2176C family
which also comes in similar Single Dual and Quad configura-
tions The EL2170CEL2176C family provides a b3 dB band-
width of 70 MHz while consuming 1 mA of supply current per
amplifier
