EL2270

70MHz/1mA Current Mode Feedback

Amplifiers

The EL2270 is a dual current-feedback

operational amplifiers which achieves

a -3dB bandwidth of 70MHz at a gain

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.

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.
