EL2001 pdf datasheet (Low Powe

The EL2001 is a low cost monolithic,
high slew rate, buffer amplifier. Built
using the Elantec monolithic
Complementary Bipolar process, this patented buffer has a
-3dB bandwidth of 70MHz, and delivers 100mA, yet draws
only 1.3mA of supply current. It typically operates from ±15V
power supplies but will work with as little as ±5V.
This high speed buffer may be used in a wide variety of
applications in military, video and medical systems. A typical
example is a general purpose op amp output current booster
where the buffer must have sufficiently high bandwidth and
low phase shift at the maximum frequency of the op amp.
Elantec's products and facilities comply with MIL-I-45208A,
