General Description
The EL2180C/EL2280C/EL2480C are single/dual/quad current-feed-
back operational amplifiers that achieve a -3dB bandwidth of 250MHz
at a gain of +1 while consuming only 3mA of supply current per
amplifier. They will operate with dual supplies ranging from ±1.5V to
±6V or from single supplies ranging from +3V to +12V. In spite of
their low supply current, the EL2480C and the EL2280C can output
55mA while swinging to ±4V on ±5V supplies. The EL2180C can out-
put 100mA with similar output swings. These attributes make the
EL2180C/EL2280C/EL2480C excellent choices for low power and/or
low voltage cable driver, HDSL, or RGB applications.
For applications where board space is extremely critical, the EL2180C
is available in the tiny 5-pin SOT23 package, with a footprint size 28%
of an 8-pin SO. The EL2480C is also available in a 24-pin LPP pack-
age. All are specified for operation over the full -40°C to +85°C
temperature range.
Single, dual, and triple versions are also available with the enable
function (EL2186C, EL2286C, and EL2386C).
