  • OPA2141: spec question about OPA2141

    Part Number: OPA2141 Hi team, 1.do we have the detail spec of the load capability for all temp range? 2.can we use TINA to simulate the load capability plot?

  • RE: TINA/Spice/OPA2141: TINA/Spice/OPA2141

    Hi Hojin, I would remove C219. A high capacitive load at the output of an OPAmp can cause instability and oscillation. C213 should also be removed. A capacitance from the -input of OPAmp to GND erodes the phase margin and also causes instability and…

  • RE: TINA/Spice/OPA2141: Trouble with OPA2141 in LTSpice

    Hi Tim, Yes we test our models in PSpice and TINA extensively. I added your schematic to the PSpice project downloaded from the web and added a simulation profile. It is attached here. OPA2141_PSPICE_AIO.zip Thanks, JC
