General Description
The EL2260C EL2460C are dual quad current feedback opera-
tional amplifiers with ^b3 dB bandwidth of 130 MHz at a gain
of ^a2 Built using the Elantec proprietary monolithic comple-
mentary bipolar process these amplifers use current mode feed-
back to achieve more bandwidth at a given gain than a conven-
tional voltage feedback operational amplifier
The EL2260C EL2460C are designed to drive a double termi-
nated 75X coax cable to video levels Differential gain and
phase are excellent when driving both loads of 500X (^k0 01%
k_{0 01 ) and double terminated 75X cables (0 025% 0 1 )}
The amplifiers can operate on any supply voltage from 4V
(g2V) to 33V (g16 5V) yet consume only 7 5 mA per amplifier
at any supply voltage Using industry standard pinouts the
EL2260C is available in 8-pin P-DIP and 8-pin SO packages
while the EL2460C is available in 14-pin P-DIP and 14-pin SO
packages
Elantec’s facilities comply with MIL-I-45208A and offer appli-
cable quality specifications For information on Elantec’s pro-
cessing see the Elantec document QRA-1 Elantec’s Process-
