400MHz GBWP Gain-of-2 Stable
Operational Amplifier
time, excellent differential gain and differential phase perfor-
mance, and a minimum of 50mA output current drive over
temperature.
The EL2074 is gain-of-2 stable with a -3dB bandwidth of
400MHz at A
voltage, only 2µA of input bias current, and a fully symmetri-
cal differential input. Like all voltage-feedback operational
amplifiers, the EL2074 allows the use of reactive or non-lin-
ear components in the feedback loop. This combination of
speed and versatility makes the EL2074 the ideal choice for
all op-amp applications at a noise gain of 2 or greater requir-
ing high speed and precision, including active filters,
integrators, sample-and-holds, and log amps. The low distor-
tion, high output current, and fast settling makes the EL2074
an ideal amplifier for signal-processing and digitizing
systems.

... It is important to note that the EL2074 has been designed so that this “extra” band- width in low-gain applications does not come at the expense of stability. As seen in the typical performance curves, the EL2074 in a gain of +2 only exhibits 1dB of peaking with a 100 load. ...

... In a gain of +2, driving 150 , with standard video test levels at the input, the EL2074 exhibits dG and dP of only 0.01% and 0.015° at NTSC and PAL. Because dG and dP vary with different DC offsets, the superior video perfor- mance of the EL2074 has been characterized over the entire DC offset range from -0 ...
