General Description
The EL2020 is a fast settling wide bandwidth amplifier opti-
mized for gains between
b
10 and
a
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 amplifi-
er
The EL2020 will drive two double terminated 75X coax cables
to video levels with low distortion Since it is a closed loop de-
vice the EL2020 provides better gain accuracy and lower distor-
tion 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 inde-
pendent of the closed loop gain taken The 50 MHz bandwidth
at unity gain only reduces to 30 MHz 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 prod-
