Overview: ® EL2180, EL2280, EL2480
Data Sheet November 14,2002 FN7055 250MHz/3mA Current Mode Feedback Amplifiers
The EL2180, EL2280, and EL2480 are single, dual, and quad currentfeedback operational amplifiers which achieve a -3dB bandwidth of 250MHz at a gain of +1 while consuming only 3mA 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 EL2480 and the EL2280 can output 55mA while swinging to ±4V on ±5V supplies. The EL2180 can output 100mA with similar output swings. These attributes make the EL2180, EL2280, and EL2480 excellent choices for low power and/or low voltage cable-driver, HDSL, or RGB applications. For applications where board space is extremely critical, the EL2180 is available in the tiny 5-pin SOT-23 package, which has a footprint 28% the size of an 8-pin SO. For single, dual, and triple applications with disable, consider the EL2186 (8-pin single), EL2286 (14-pin dual), or EL2386 (16-pin triple). For lower power applications where speed is still a concern, consider the EL2170/EL2176 family which also es in similar single, dual, and quad configurations. The EL2170/EL2176 family provides a -3dB bandwidth of 70MHz while consuming 1mA of supply current per amplifier.
