EL5156, EL5157, EL5256, EL5257
<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 10kV/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 batter-powered equipment. The capability to
output as much as 50mA this family is comfortable with
demanding load conditions.
Single amplifiers are offered 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 -40C to +85C.
Features
610MHz -3dB bandwidth, 240MHz 0.1dB bandwidth
700V/s slew rate
Very high open loop gains 96dB
Low supply current = 6mA
Single supplies from 5V to 10V
Dual supplies from 2.5V to 5V
Fast disable on the EL5156 and EL5256
