70MHz/1mA Current Mode Feedback
Amplifiers
-3dB bandwidth of 70MHz at a gain of +1 while consuming
only 1mA 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 EL2270 and the EL2470 can output
55mA while swinging to ±4V on ±5V supplies. The EL2170
can output 100mA with similar output swings. These
attributes make the EL2170, EL2270, and EL2470 excellent
choices for low power and/or low voltage cable-driver, HDSL,
or RGB applications.
For applications where board space is extremely critical, the
EL2170 is available in the tiny 5-pin SOT-23 package, which
has a footprint 28% the size of an 8-pin SO. The EL2170,
EL2270, and EL2470 are each also available in industry
standard pinouts in PDIP and SO packages.
For single and dual applications with disable, consider the
EL2176 (8-pin single) or EL2276 (14-pin dual). For higher
speed applications where power is still a concern, consider
the EL2180/EL2186 family which also comes in similar
single, dual, triple and quad configurations. The
EL2180/EL2186 family provides a -3dB bandwidth of
250MHz while consuming 3mA of supply current per
amplifier.
The EL2170, EL2270, and EL2470 are
single/dual/quad current-feedback
operational amplifiers which achieve a
