70MHz/1mA Current Mode Feedback Amp
w/Disable
The EL2276 is a dual current-feedback operational amplifier
which achieves a -3dB bandwidth of 70MHz at a gain of +1
while consuming only 1mA of supply current per amplifier. It
will operate with dual supplies ranging from ±1.5V to ±6V, or
from single supplies ranging from +3V to +12V. The EL2276
also includes 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 EL2276 can output 55mA while swinging to ±4V
on ±5V supplies. These attributes make the EL2276
excellent choice for low power and/or low voltage cable-
driver, HDSL, or RGB applications.
Ordering Information
NOTE: Intersil Pb-free products employ special Pb-free material sets;
molding compounds/die attach materials and 100% matte tin plate
termination finish, which are RoHS compliant and compatible with
both SnPb and Pb-free soldering operations. Intersil Pb-free products
are MSL classified at Pb-free peak reflow temperatures that meet or
exceed the Pb-free requirements of IPC/JEDEC J STD-020.

... CMOS outputs or open-collector TTL. When enabled, supply current does vary somewhat with the voltage applied at ENABLE. For example, with the supply voltages of the EL2276 at ±5V, if ENABLE is tied to -5V (rather than ground) the supply current will increase about 15% to 2.3mA. ...

... EL2276 has an input voltage range that extends to within 1V of either supply. So, for example single +5V supply, the EL2276 has an input range which spans from 1V to 4V. The output range of the EL2276 is also quite large, extending to within 1V of the supply rail ±5V supply, the output is therefore capable of swinging from -4V to +4V ...
