Hi all,
I'm attempting to simulate a circuit using the OPA810 because it has the supply voltage, slew rate, and gain-bandwidth product I need for my application. However, when simulating in Allegro PSpice Simulator (via Design Entry CIS 17.2), I can't do much that is useful with it, or Allegro will get stuck trying to find the bias point.
When I say "do something useful", I mean I can get a believable transient simulation if I ground both inputs (or tie them both to a reference voltage), but the moment I separate them, such as in a simple voltage follower with a constant input, PSpice is unable to converge during the bias point calculation.
I've attached such a simple circuit in hopes that someone can show me what I'm doing wrong. The model I'm using was obtained from www.ti.com/.../sbomb79.
Thanks!OPA810Test_2021-02-24.zip
