100MHz Current Feedback Amplifier
The EL2120 is a wideband current
feedback amplifier optimized for video
performance. Its 0.01% differential
gain and 0.03 degree differential phase performance when
at ±5V supplies exceeds the performance of other amplifiers
running on ±15V supplies. Operating on ±8 to ±15V supplies
reduces distortions to 0.01% and 0.01 degrees and below.
The EL2120 can operate with supplies as low as ±2.5V or a
single +5V supply.
Being a current feedback design, bandwidth is a relatively
constant 100MHz over the ±1 to ±10 gain range. The
EL2120 has been optimized for flat gain over frequency and
all characteristics are maintained at positive unity gain.
Because the input slew rate is similar to the 700V/µs output
slew rate the part makes an excellent high-speed buffer.
The EL2120 has a superior output disable function. Time to
enable or disable is 50ns and does not change markedly
with temperature. Furthermore, in disable mode the output
does not draw excessive currents when driven with
1000V/µs slew rates. The output appears as a 3pF load
when disabled.
