EL2160
180MHz Current Feedback Amplifier
The EL2160 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 EL2160 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 sup-
ply voltage. Using industry-standard pinouts, the EL2160 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 -40C to +85C temperature range. For dual and quad
applications, please see the EL2260/EL2460 datasheet.
