Other Parts Discussed in Thread: INA138, TINA-TI, INA180
my customer is using INA180A2QDBVRQ1 (current sense amplifier) in their project.While using this model in SIMetrix 8.3 for simulation work, with PWM signal input the output voltage is decreasing if the current load starts to consume (see images below):
In other to do a cross check the same simulation with the same circuit was done with INA138 current sense amplifier; as can be seen in the image below the voltage is increasing from 0 to some extent for its respective current load consumption
Could you please verify was is happening with the first simulation and let us know the reason for this simulation result?
What could be done to have a correct simulation result?
Can this be related to the Pspice model itself (downloaded on ti.com)?
