Product Number: AD8051
I have been using this SPICE model for the AD8051: https://www.analog.com/en/products/ad8051.html#product-overview
I notice that when used as a voltage follower, if given an input less than around 0.4V and no output load, the output no longer follows the input. I am trying to narrow down whether this is an issue with the SPICE model, an issue with TINA-TI, or normal behavior of the amplifier.. Perhaps something to do with the voltage swing, or common mode input? I have also had similar issues with this model in LTSpice.
Here is how I set it up by using the TINA-TI new macro wizard:
I used a generic op-amp symbol, following the node assignments in the .cir file.
For the results I get 509.75mV output, for a 300mV input.
