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.
