250MHz/3mA Current Mode Feedback Amp w/Disable

General Description

The EL2186C/EL2286C 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 EL2186C/EL2286C also

include a disable/power-down feature which reduces current con-

sumption to 0mA while placing the amplifier output in a high

impedance state. In spite of its low supply current, the EL2286C can

output 55mA while swinging to ±4V on ±5V supplies. The EL2186C

can output 100mA with similar output swings. These attributes make

the EL2186C/EL2286C 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

EL2180C (8-Pin Single), EL2280C (8-Pin Dual) or EL2480C (14-Pin

Quad). For lower power applications where speed is still a concern,

consider the EL2170C/El2176C family which also comes in similar

Single, Dual and Quad configurations. The EL2170C/EL2176C fam-

ily provides a -3dB bandwidth of 70MHz while consuming 1mA of

supply current per amplifier.
