spice model for THS4531, THS4531A and THS4532

Other Parts Discussed in Thread: THS4531, THS4531A, THS4524, THS4522, THS4521

I think there are errors in the spice models for the THS4531, the THS4531A and TH4532.

The THS4531.TSC example (in EXAMPLES\TI Test Circuits) yields an operating current of almost 50mA, yet the data sheet claims an operating current of 250uA.

If you let the SD\ pin float, it is 250uA but the GBW is nowhere near correct.

When I change the THS4531 to the THS4531A or THS4531, the same problem happens.


When I use the PSPICE model(s) for all three in a PSPICE-capable simulator, the same problem happens.

FYI, the ths4521_ths4522_ths4524.TSC does give both the correct operating current and bandwidth with the SD\ pin tied to V+.
