EL2170, EL2270, EL2470

70MHz/1mA Current Mode Feedback

Amplifiers

The EL2170, EL2270, and EL2470 are

single/dual/quad current-feedback

operational amplifiers which achieve a

-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.
