270MHz Ultra-Accurate Amplifiers
The EL5152, EL5153, EL5252, and EL5455 are 270MHz
bandwidth -3dB voltage mode feedback amplifiers with DC
accuracy of <0.01%, 1mV offsets and 50kV/V open loop
gains. These amplifiers are ideally suited for applications
ranging from precision measurement instrumentation to
high-speed video and monitor applications demanding
higher linearity at higher frequency. Capable of operating
with as little as 3.0mA of current from a single supply ranging
from 5V to 12V dual supplies ranging from ±2.5V to ±5.0V
these amplifiers are also well suited for handheld, portable
and battery-powered equipment.
Single amplifiers are offered in SOT-23 packages and duals
in a 10 Ld MSOP package for applications where board
space is critical. Quad amplifiers are available in a 14 Ld SO
package. Additionally, singles and duals are available in the
industry-standard 8 Ld SO. All parts operate over the
industrial temperature range of -40°C to +85°C.

Differential Output Instrumentation Amplifier
The addition of a third amplifier to the conventional three
amplifier Instrumentation Amplifier introduces the benefits of
differential signal realization, specifically the advantage of
using common mode rejection to remove coupled noise and
ground-potential errors inherent in remote transmission. This
configuration also provides enhanced bandwidth, wider
output swing and faster slew rate than conventional three
amplifier solutions with only the cost of an additional
amplifier and few resistors.
