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.
