70MHz/1mA Current Mode Feedback
Amplifiers
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.
For applications where board space is extremely critical. The
EL2270 is available in industry standard pinouts in SO
package.
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.
Ordering Information
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.
