70MHz/1mA Current Mode Feedback
Amplifiers
Features
• Dual topologies
The EL2270 is a dual current-feedback
operational amplifiers which achieves
a -3dB bandwidth of 70MHz at a gain
• 1mA supply current (per amplifier)
• 70MHz -3dB bandwidth
• Low cost
of +1 while consuming only 1mA of supply current per
amplifier. It will operate with dual supplies ranging from
±1.5V to ±6V, or from single supplies ranging from +3V to
+12V. In spite of its low supply current, the EL2270 can
output 55mA while swinging to ±4V on ±5V supplies. These
attributes make the EL2270 an excellent choice for low
power and/or low voltage cable-driver, HDSL, or RGB
applications.
• 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 - 55mA
• Also available with disable in single (EL2176) & dual
(EL2276)
For applications where board space is extremely critical. The
EL2270 is available in industry standard pinouts in SO
package.
• Higher speed EL2180/EL2186 family available
(3mA/250MHz) in single, dual, and quad
• Pb-free available
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.
Applications
• Low power/battery applications
• HDSL amplifiers
• Video amplifiers
• Cable drivers
• RGB amplifiers
Ordering Information
• Test equipment amplifiers
• Current to voltage converters

NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which is compatible with both SnPb and
Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed
the Pb-free requirements of IPC/JEDEC J Std-020B.
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
