250MHz/3mA Current Mode Feedback
Amplifiers
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 EL2480 and the EL2280 can
output 55mA while swinging to ±4V on ±5V supplies. The
EL2180 can output 100mA with similar output swings. These
attributes make the EL2180, EL2280, and EL2480 excellent
choices for low power and/or low voltage cable-driver, HDSL,
or RGB applications.
For applications where board space is extremely critical, the
EL2180 is available in the tiny 5-pin SOT-23 package, which
has a footprint 28% the size of an 8-pin SO.
For single, dual, and triple applications with disable, consider
the EL2186 (8-pin single), EL2286 (14-pin dual), or EL2386
(16-pin triple). For lower power applications where speed is
still a concern, consider the EL2170/EL2176 family which
also comes in similar single, dual, and quad configurations.
The EL2170/EL2176 family provides a -3dB bandwidth of
70MHz while consuming 1mA of supply current per amplifier.
