EL2130
85MHz Current Feedback Amplifier
The EL2130 is a wideband current
mode feedback amplifier optimized for
gains between -10 and +10 while
operating on 5V power supplies. Built using Elantec's
Complementary Bipolar process, this device exhibits -3dB
bandwidths in excess of 85MHz at unity gain and 75MHz at
a gain of two. The EL2130 is capable of output currents in
excess of 50mA giving it the ability to drive either double or
single terminated 50
coaxial cables.
Exhibiting a Differential Gain of 0.03% and a Differential
Phase of 0.1 at NTSC and PAL frequencies, the EL2130 is
an excellent low cost solution to most video applications.
In addition, the EL2130 exhibits very low gain peaking,
typically below 0.1dB to frequencies in excess of 40MHz as
well as 50ns settling time to 0.2% making it an excellent
choice for driving flash A/D converters.
The device is available in the plastic 8-pin narrow-body small
outline (SO) and the 8-pin mini DIP packages, and operates
over the temperature range of 0C to +75C
