General Description
The EL2074C is a precision voltage-feedback amplifier featuring a
400MHz gain-bandwidth product, fast settling time, excellent differ-
ential gain and differential phase performance, and a minimum of
50mA output current drive over temperature.
The EL2074C is gain-of-2 stable with a -3dB bandwidth of 400MHz
at AV = +2. It has a very low 200V of input offset voltage, only 2A
of input bias current, and a fully symmetrical differential input. Like
all voltage-feedback operational amplifiers, the EL2074C allows the
use of reactive or non-linear components in the feedback loop. This
combination of speed and versatility makes the EL2074C the ideal
choice for all op-amp applications at a noise gain of 2 or greater
requiring high speed and precision, including active filters, integra-
tors, sample-and-holds, and log amps. The low distortion, high output
current, and fast settling makes the EL2074C an ideal amplifier for
signal-processing and digitizing systems.
