The SHC605 is a monolithic high-speed, high accu-
racy track-and-hold amplifier. It combines fast acqui-
sition and low distortion to provide a complete solu-
tion for a wide range of sampling applications. Its new
proprietary closed-loop architecture provides a single-
chip solution to many data acquisition problems for-
merly requiring more than one device. Noninverting,
inverting, and differential gain configurations are easy
to apply with the SHC605. An on-board logic refer-
ence circuit makes the SHC605 compatible with both
single-ended and differential ECL or TTL clock in-
puts. 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.
