General Description

The EL2130 is a wideband current mode feedback amplifier op-

timized for gains between

b

10 and

a

10 while operating on

g

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

polar process this device exhibits

b

3 dB bandwidths in excess

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 50X

coaxial cables

Exhibiting a Differential Gain of 0 03% and a Differential

Phase of 0 1 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 0 1 dB to frequencies in excess of 40 MHz as well as 50

ns settling time to 0 2% making it an excellent choice for driv-

ing flash A D converters

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

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

over the temperature range of 0 C to

a

75 C

Applications

Video amplifier

Video distribution amplifier
