Dual Quad 130 MHz Current Feedback Amplifiers
General Description
The EL2260C EL2460C are dual quad current feedback opera-
tional amplifiers with
of
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 75
phase are excellent when driving both loads of 500
The amplifiers can operate on any supply voltage from 4V
(
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-
