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 75Ω coax cable to video levels. Differential gain
and phase are excellent when driving both loads of 500Ω
(< 0.01%/< 0.01°) and double terminated 75Ω 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.
