The EL2186/EL2286 are single/dual current-feedback 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. The EL2186/EL2286 also include a disable/power-down feature which reduces current consumption to 0mA while placing the amplifier output in a high impedance state. In spite of its low supply current, the EL2286 can output 55mA while swinging to ±4V on ±5V supplies. The EL2186 can output 100mA with similar output swings. These attributes make the EL2186/EL2286 excellent choices for low power and/or low voltage cabledriver, HDSL, or RGB applications.

For Single, Dual and Quad applications without disable, consider the EL2180 (8-Pin Single), EL2280 (8-Pin Dual) or EL2480 (14-Pin Quad). For lower power applications where speed is still a concern, consider the EL2170/EL2176 family which also comes 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.
