GENERAL DESCRIPTION

The SPT9101 is a high-speed track-and-hold amplifier de-

signed for a wide range of use. The SPT9101 is capable of

sampling at speeds up to 125 MSPS with resolutions ranging

from 8 to 12 bits. Trim programmable internal hold and

compensation capacitors provide for optimized input band-

width and slew rate versus noise performance.

The performance of this device makes it an excellent front

end driver for a wide range of ADCs on the market today.

Significant improvements in dynamic performance can be

achieved by using this device ahead of virtually all ADCs that

do not have an internal track-and-hold.

The SPT9101 is offered in 20-lead SOIC and LCC packages

over the industrial temperature range and in die form. Contact

the factory for military and /833 package options.
