EL2260C/EL2460C
Dual/Quad 130 MHz Current Feedback Amplifiers
Features
# 130 MHz 3 dB bandwidth
General Description
The EL2260C/EL2460C are dual/quad current feedback opera-
b
tional amplifiers with 3 dB bandwidth of 130 MHz at a gain
of 2. Built using the Elantec proprietary monolithic comple-

The EL2260C/EL2460C are designed to drive a double termi-
nated 75X coax cable to video levels. Differential gain and
