DescriptionThe 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 EL2170, EL2270, and EL2470 family provides a -3dB bandwidth of 250MHz while consuming 3mA of supply current per amplifier.
