EL2260, EL2460
Dual/Quad 130MHz Current Feedback
Amplifiers
The EL2260/EL2460 are dual/quad
current feedback operational amplifiers
with -3dB bandwidth of 130MHz at a
gain of +2. Built using the Elantec proprietary monolithic
complementary bipolar process, these amplifiers use current
mode feedback to achieve more bandwidth at a given gain
than a conventional voltage feedback operational amplifier.
The EL2260/EL2460 are designed to drive a double
terminated 75
coax cable to video levels. Differential gain
and phase are excellent when driving both loads of 500
(< 0.01%/< 0.01) and double terminated 75
cables
(0.025%/0.1).
The amplifiers can operate on any supply voltage from 4V
(2V) to 33V (16.5V), yet consume only 7.5mA per
amplifier at any supply voltage. Using industry standard
pinouts, the EL2260 is available in 8-pin PDIP and 8-pin SO
packages, while the EL2460 is available in 14-pin PDIP and
14-pin SO packages.
Elantec's facilities comply with MIL-I-45208A and offer
applicable quality specifications. For information on Elantec's
processing, see the Elantec document, QRA-1: Elantec's
Processing--Monolithic Products.
