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.

This device provides an analog designer with a low cost

single-to-differential THA amplifier for interfacing differential

and single-ended ADCs.

The SPT9110 is offered in a 28-lead SOIC package in the

industrial temperature range.
