General Description
The EL2030 is a very fast wide bandwidth amplifier optimized
for gains between
b
10 and
a
10 Built using the Elantec mono-
lithic Complementary Bipolar process this amplifier uses cur-
rent mode feedback to achieve more bandwidth at a given gain
than a conventional voltage feedback operational amplifier
Due to its wide operating supply range (
g
15V) and extremely
high slew rate of 2000 V
ms
the EL2030 drives
g
10V into 200X
at a frequency of 30 MHz while achieving 110 MHz of small
signal bandwidth at A

V
e a
2 When used as a unity gain
buffer the EL2030 has a 120 MHz bandwidth with the gain
precision and low distortion of closed loop buffers
The EL2030 features extremely low differential gain and phase
a low noise topology that reduces noise by a factor of 2 over
competing amplifiers and settling time of 40 ns to 0 25% for a
10V step The output is short circuit protected In addition da-
tasheet limits are guaranteed for
g
5V and
g
15V supplies
