EL2120C

The EL2120C is a wideband current feedback amplifier optimized for video performance. Its 0.01% differential gain and 0.03 degree differential phase performance when at g5V supplies exceeds the performance of other amplifiers running on g15V supplies. Operating on g8 to g15V supplies reduces distortions 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 constant 100 MHz over the g1 to g10 gain range. The EL2120C 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 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.
