DESCRIPTION

The SHC605 is a monolithic high-speed, high accu­racy track-and-hold amplifier. It combines fast acqui­sition and low distortion to provide a complete solu­tion for a wide range of sampling applications. Its new
proprietary closed-loop architecture provides a single­chip solution to many data acquisition problems for­merly requiring more than one device. Noninverting,
inverting, and differential gain configurations are easy
to apply with the SHC605. An on-board logic refer­ence circuit makes the SHC605 compatible with both
single-ended and differential ECL or TTL clock in­puts. An internal track-mode lockout circuit allows
edge-triggered operation in data acquisition systems.
The SHC605 is available in a SO-16 surface-mount
package specified for the –40C to +85C industrial
temperature range.

This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.

ESD damage can range from subtle performance degrada­tion to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet its
published specifications.
