GENERAL DESCRIPTION
The HOS-OSO, HOS-OSOA, and HOS-OSOC op amps are very
high speed wideband operational amplifiers designed to comple-
ment the Analog Devices' lines of high speed data acquisition
products. They feature a lOOMHz gain bandwidth product; slew
rate of 300V/l-ls; and settling time of 80ns to ~O.l%.
The HOS-OSOA, HOS-OSO, and HOS-OSOC have typical input
offset voltages of lOmV, 2SmV, and 4SmV, respectively.

All models have a rated output of ~ lOOmA minimum, and an
exceptional noise spec of only 71-Vl rms, dc to 2MHz; they are
ideally suited for a broad range of video applications.

he conversion speed of the D/ A can be limited by the settling
me of the output amplifier, so it has become essential to select
dn op amp whose settling time is compatible with the D/ A
converter.

The increased emphasis on settling time has, in some cases,
created a preoccupation with slew rates in the minds of some
designers. But slew rate is only one component in establishing
settling time.
The amount of overshoot, and the ringing which are present at
the end of a step function change also have an effect. These
parameters, in turn, are influepced by the bandwidth (or lack of
