The EL2020 is a fast settling, wide
bandwidth amplifier optimized for
gains between -10 and +10. Built using
the Elantec monolithic Complementary Bipolar process, this
amplifier uses current mode feedback to achieve more
bandwidth at a given gain then a conventional voltage
feedback operational amplifier.
The EL2020 will drive two double terminated 75Ω coax
cables to video levels with low distortion. Since it is a closed
loop device, the EL2020 provides better gain accuracy and
lower distortion than an open loop buffer. The device
includes output short circuit protection, and input offset
adjust capability.
The bandwidth and slew rate of the EL2020 are relatively
independent of the closed loop gain taken. The 50MHz
bandwidth at unity gain only reduces to 30MHz at a gain of
10. The EL2020 may be used in most applications where a
conventional op amp is used, with a big improvement in
speed power product.
