Other Parts Discussed in Thread: OPA2145
I'm looking to use the OPA145 (or OPA2145) in a new design which uses very low Voltages. The supply rails would be +/-3.3V. According to the data sheet the part looks like it should be good down to +/-2.25V. However when I tried using the spice model, I can't get the part to work properly below about +/-5V. Is this a known bug in the model or does the part really have a problem working down at low supply Voltages..? I've tried both the Tina spice tool and the LTSpice tool but they both give identical results.
