E L2276

70MHz/1mA Current Mode Feedback Amp w/Disable

DATASHEET

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.

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
