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/s 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/s slew rates. The output appears as a 3pF load when disabled.
