Description

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^o) and double terminated 75Ω cables (0.025%/0.1^o). 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.
