General Description
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
b
3 dB bandwidth of
70 MHz and delivers 100 mA yet draws only 1 3 mA of supply
current It typically operates from
g
15V power supplies but
will work with as little as
g
5V
This high speed buffer may be used in a wide variety of applica-
tions 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
and other applicable quality specifications For information on
Elantec's processing see the Elantec document QRA-1 Elan-
tec's Processing Monolithic Integrated Circuits

Note 1 If the input exceeds the ratings shown (or the supplies) or if the input to output voltage exceeds

7 5V then the input
current must be limited to
g
50 mA See the applications section for more information
Note 2 The maximum power dissipation depends on package type ambient temperature and heat sinking See the characteristic
curves for more details
Note 3 A heat sink is required to keep the junction temperature below the absolute maximum when the output is short circuited
