The EL2120C is a wideband current feedback amplifier opti-  
mized for video performance. Its 0.01% differential gain and

15V supplies. Operating on 8 to 15V supplies reduces dis-  
tortions to 0.01% and 0.01 degrees and below. The EL2120C can

stant 100 MHz over the 1 to 10 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.

# Available in small SO-8 package  
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.

# Video gain block  
# Residue amplifier  
# Multiplexer  
# Current to voltage converter  
# Coax cable driver with gain of 2  
# ADC driver
