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 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 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
dual and quad applications, please see the EL2260C/EL2460C
datasheet.
