This webpage:
has a "macromodel" (which is a SPICE model) for the MAX4173T. The
difference between the 'T' and the 'H' version seems to be the part's
voltage gain. If you can only use the 'H' version, it might be possible to
modify the 'T' version's macromodel.
Macromodels are models of simplified versions of the actual circuitry.
Sometimes a block, such as an op-amp, is represented by a VCVS, which
simulates faster than a couple dozen transistors that actually comprise the
op-amp.
This macromodel is a SPICE "subcircuit", so you would use it as a
subcircuit. There must be hundreds of messages already in this group about
how to use a subcircuit model in an LTspice simulation.
This webpage:
has an Orcad (PSPICE) library for the same part. The model looks very
similar. LTspice is very compatible with PSPICE, so that one probably
works just fine too.
