EL2073
200MHz Unity-Gain Stable Operational
Amplifier
The EL2073 is a precision voltage-
feedback amplifier featuring a 200MHz
gain-bandwidth product, fast settling
time, excellent differential gain and differential phase
performance, and a minimum of 50mA output current drive
over temperature.
The EL2073 is unity-gain stable with a -3dB bandwidth of
400MHz. 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
EL2073 allows the use of reactive or non-linear components
in the feedback loop. This combination of speed and
versatility makes the EL2073 the ideal choice for all op-amp
applications requiring high speed and precision, including
active filters, integrators, sample-and-holds, and log amps.
The low distortion, high output current, and fast settling
makes the EL2073 an ideal amplifier for signal-processing
and digitizing systems.
