® EL2270 Data Sheet July 13, 2004 FN7053.1 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
