EL2186, EL2286

250MHz/3mA Current Mode Feedback

Amp w/Disable

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 cable-

driver, 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.
