![]() I think this simulator is buggy, and the fact you succeeded with TL084 is the evidence. I attach now two snapshots of my actual simulation that seem to work, but even so it happens that the simulation crashes without an evident specific reason. ![]() In the meantime I arrived to obtain meaningful behaviour by connecting ALL package units to power lines, though it would be enough to have connected a single unit. I have a "database invalid size" error that I wasn't able to fix even by a wipe-all disinstallation (registry included) and successive reinstallation, though it appears it makes no harm. Indicate me a possible error or an alternative very common 4 x jfet op-amp building block that It seems to me the simulator has some bug dealing with those op-amps, can anybody please ![]() A visual cross inspection showed that the SPICE I thought that the SPICE model was broken, andĭownloaded some up to date from TI site. I made some other test with other largely used op amps and saw that these coming from 741 The TL084 with a CA3130 and all worked well at first. ![]() Work but behaving erratically, halting on errors that could not be recognized. Stick it to the most negative potential, the battery (12V) minus. Ground symbol on a generic node like the op-amp output because virtual instruments gaveįaulty readings, even using floating instruments as a tester. At first it seemed that it wasn't allowed to put analog ![]() I have used TI TL08x op amps all the life long, so I was very disappointed when I saw lots The initial idea was to use it to obtain an analog ground for a battery operated equipment. VCC to +VCC following the supply midpoint-value obtained with two 10k resistors. So I began simulating a simple op-amp follower, powered by a single supply from I'm a retired engineer who is willing to learn using NI CDS11.Īs I'm used to start bottom-up I'm trying to simulate some simple circuits at first. ![]()
