70MHz/1mA Current Mode Feedback
Amplifiers
Features
• Single (EL2170), dual (EL2270) & quad (EL2470)
topologies
The EL2170, EL2270, and EL2470 are
single/dual/quad current-feedback
operational amplifiers which achieve a
• 1mA supply current (per amplifier)
• 70MHz -3dB bandwidth
-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.
• Tiny SOT23-5 package (EL2170)
• Low cost
• Single- and dual-supply operation down to ±1.5V
• 0.15%/0.15° diff. gain/diff. phase into 150Ω
• 800V/µs slew rate
• Large output drive current - 100mA (EL2170), 55mA
(EL2270), 55mA (EL2470)
• Also available with disable in single (EL2176) & dual
(EL2276)
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.
• Higher speed EL2180/EL2186 family available
(3mA/250MHz) in single, dual, and quad
Applications
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.
• Low power/battery applications
• HDSL amplifiers
• Video amplifiers
• Cable drivers
• RGB amplifiers
• Test equipment amplifiers
• Current to voltage converters
