Hello experts,
We are trying to smulate the TLV9162 model given in https://www.ti.com/product/TLV9162 , usder "Design Tools & Simulation"
We tried a simple voltage follower with a non inverting input , giving it a sinosoidal input of 5 KHz grequency , with an offset of 1v and amplitude of 1v in single supply configurtion with V+ of 3.33v.
Notice that as the input approches near 0v(less than approx 100 mv) , the output gets unstable..
Could you kindly conform if we are violating the opamp parameters in some way.?
We tried the same curcuit with a supply of 15v with similar results
Hey AK,
This is not the intended behavior. I believe there is an internal clamping structure that is causing this behavior. We will work to resolve this. In the meantime, I would try to keep the output voltage away from the linear range of the output stage. I believe in this model the worst typical spec was targeted, which was 85mV from V-.
As another point, we do not support LTspice, and this model works somewhat better in TINA-TI (see below) where this behavior is only seen on the first instance of going outside of the linear output range.
Best,
Jerry
