GENERAL DESCRIPTION

The SPT9110 is a single-to-differential track-and-hold amplifier. 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.
