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

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.
