GENERAL DESCRIPTION
The SPT9110 is a single-to-differential track-and-hold ampli-
fier. It can be operated as a single-end THA only or, in full
configuration, as a single-to-differential THA. An internal
reference provides the common-mode voltage for the single-
to-differential output stage. The THA, inverter and reference
have separate power supply pins so each can be optionally
powered up and used.
