Data Sheet July 2, 2004

<1mV Voltage Offset, 600MHz Amplifiers

The EL5156, EL5157, EL5256, and
EL5257 are 600MHz bandwidth -3dB

voltage mode feedback amplifiers with
DC accuracy of <0.01%, 1mV offsets and 40kV/V open loop
gains. These amplifiers are ideally suited for applications
ranging from precision measurement instrumentation to high
speed video and monitor applications demanding the very
highest linearity at very high frequency. Capable of operating
with as little as 6.0mA of current from a single supply ranging
from 5V to 12V and dual supplies ranging from ±2.5V to
±5.0V these amplifiers are also well suited for handheld,
portable and battery-powered equipment. With their
capability to output as much as 140mA, member of this
family is comfortable with demanding load conditions.

Single amplifiers are available in SOT-23 packages and
duals in a 10-pin MSOP package for applications where
board space is critical. Additionally, singles and duals are
available in the industry-standard 8-pin SO package. All
parts operate over the industrial temperature range of -40°C
to +85°C.
