100MHz Current Feedback Amplifier

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.

Simplified Schematic

The EL2120 is a wideband current

feedback amplifier optimized for video

performance. Its 0.01% differential
