Low Power, 180MHz Buffer Amplifier
The EL2002 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 180MHz, and delivers 100mA, yet draws
only 5mA 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. Typical
examples include fast op-amp output current boosters,
coaxial cable drivers and A/D converter input buffers.
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:
Elantec's Processing, Monolithic Integrated Circuits.
Features
• 180MHz bandwidth
• 2000V/µs slew rate
• Low bias current, 3µA typical
• 100mA output current
• 5mA supply current
• Short circuit protected
• Low cost
• Stable with capacitive loads
• Wide supply range ±5V to ±15V
• No thermal runaway
Applications
• Op amp output current booster
• Cable/line driver
• A/D input buffer
• Isolation buffer
