PRODUCT DESCRIPTION
The Analog Devices ADSOS), ADSOSK and ADSOSS are
monolithic operational amplifiers that are specifically designed
for applications requiring high slew rate and fast settling time
to high accuracy. The ADSOS achieves a minimum slew rate
of 120V/l1sec, provides an adjustable unity gain bandwidth
product of 4MHz to 10MHz, and settles to 0.1 % in 800nsec.
In addition to its superior dynamic characteristics, the ADSOS
maintains high gain, maximum offset voltage drift of lSp.V/C,
maximum bias currents of 2SnA and high output swing.

often more dependent upon the test circuit than the
amplifier's ability to perform.
The ADSOS provides performance superior to most high
speed IC op amps and comparable to modular versions.
Because of its monolithic construction, however, its cost is
significantly below that of modules, and becomes even lower
in large quantities.
All the circuits are supplied in the TO-100 package. The

voltage for a large input step change and can be related to
the full power response (fp) by the relationship. . . . .
