General Description
The EL2160C is a current feedback operational amplifier with -3dB bandwidth of 130MHz at a gain of +2. Built using the Elantec proprietary monolithic complementary bipolar process, this amplifier uses current mode feedback to achieve more bandwidth at a given gain than a conventional voltage feedback operational amplifier. The EL2160C is 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 amplifier can operate on any supply voltage from 4V (±2V) to 33V (±16.5V), yet consume only 8.5mA at any supply voltage. Using industry-standard pinouts, the EL2160C is available in 8-pin PDIP and SO packages, as well as a 16-pin SO (0.300") package. All are specified for operation over the full -40°C to +85°C temperature range. For d u a l and quad applications, please see the EL2260C/EL2460C datasheet.
