General Description

The EL2130 is a wideband current mode feedback amplifier op-

g

5V power supplies Built using Elantec’s Complementary Bi-

of 85 MHz at unity gain and 75 MHz at a gain of two The

EL2130 is capable of output currents in excess of 50 mA giving

it the ability to drive either double or single terminated 50

X

coaxial cables

Exhibiting a Differential Gain of 003% and a Differential

Phase of 01 at NTSC and PAL frequencies The EL2130 is an

excellent low cost solution to most video applications

In addition the EL2130 exhibits very low gain peaking typical-

ly below 01 dB to frequencies in excess of 40 MHz as well as 50

ns settling time to 02% making it an excellent choice for driv-

ing flash AD converters

The device is available in the plastic 8-lead narrow-body small

outline (SO) and the 8-pin mini DIP packages and operates
