EL2120C

100 MHz Current Feedback Amplifier

General Description

The EL2120C is a wideband current feedback amplifier opti-

mized for video performance Its 0 01% differential gain and

0 03 degree differential phase performance when at

plies exceeds the performance of other amplifiers running on

tortions to 0 01% and 0 01 degrees and below The EL2120C can

operate with supplies as low as

Being a current feedback design bandwidth is a relatively con-

stant 100 MHz over the

has been optimized for flat gain over frequency and all charac-

teristics are maintained at positive unity gain Because the in-

put slew rate is similar to the 700 V

part makes an excellent high-speed buffer

The EL2120C has a superior output disable function Time to

enable or disable is 50 ns and does not change markedly with

temperature Furthermore in disable mode the output does not

draw excessive currents when driven with 1000 V

The output appears as a 3 pF load when disabled
