Okay,
Here is an interesting one. I've made up this SPICE OP-AMP model for a Texus TLV2442 Op Amp (as per the data sheet). I'm using Microcap. The AC response is fine if you use a split supply, like +/- 10v. But, on a +5/0v supply, the AC response is the same, but the reported gain is something silly (like -80dB).
The op-amp is designed for single supply
use. Is this a model problem or a limitation
of the SPICE model for op-amps.
Has anyone else had this split supply/single supply problem with SPICE op-amp models?
What do I think of Microcrap....Hmmm...:sad:
