General Description
The EL2073C is a precision voltage-feedback amplifier featuring a
200MHz 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 EL2073C 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 EL2073C allows the use of reac-
tive or non-linear components in the feedback loop. This combination
of speed and versatility makes the EL2073C 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 EL2073C
an ideal amplifier for signal-processing and digitizing systems.
