TI just confirmed that their model is crap (actually I would prefer
them not offering a model at all in that case!).

You were requesting the information about OPA349 Spice macro model. Our
OPA349 macromodel is not a very good one. It was written 5 years ago
and I've found that it does have some problems (Especially Low Voltage
problems,less than 3Volts) .Sorry for the inconvenience caused.

You might want to consider using the TLV2401 device and the
specifications are almost similar to OPA349. The TLV2401 device has a
Spice model and it can be downloaded from TI website
(http://focus.ti.com/docs/prod/folders/print/tlv2401.html#productmodels
).

I'm now simulating with the TLV2401 model, which works. However, the
real circuit will use a OPA349, because my supply is less than 2.5V
(the minimum for TLV2401).
