General Description

The EL2260C/EL2460C are dual/quad current feedback operational amplifiers with

a

of

2. Built using the Elantec proprietary monolithic complementary bipolar process, these amplifers use current mode feedback to achieve more bandwidth at a given gain than a conventional voltage feedback operational amplifier.

The EL2260C/EL2460C are designed to drive a double terminated 75X coax cable to video levels. Differential gain and phase are excellent when driving both loads of 500X (

k

0.01§) and double terminated 75X cables (0.025%/0.1§).

The amplifiers can operate on any supply voltage from 4V

g

(

2V) 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 applicable quality specifications. For information on Elantec’s processing, see the Elantec document, QRA-1: Elantec’s Process-
