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 g5V sup-
plies exceeds the performance of other amplifiers running on
g15V supplies Operating on g8 to g15V supplies reduces dis-
tortions to 0 01% and 0 01 degrees and below The EL2120C can
operate with supplies as low as g2 5V or a single a5V supply
Being a current feedback design bandwidth is a relatively con-
stant 100 MHz over the g1 to g10 gain range The EL2120C
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 ms output slew rate the
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 ms slew rates
The output appears as a 3 pF load when disabled
