  RE: OPA313: current sensing circuit Vref

  Hello, Vref is used to bias up the output voltage to mid supply. If Vref is equal to ground then the output voltage will try to swing negative during negative load currents. If you customer has bidirectional load currents and they are using a single...

  RE: CIRCUIT060007: Bidirectional low-side op amp configuration questions

  Hi Lucas, I have a few questions concerning the configuration of the op amp in this application as well questions surrounding the choice of op amp. 1. Would there be consequences of swapping the inputs to U1? (positive input to ground side of the...

  RE: TINA/Spice/OPA313: Increase Phase Margin

  Hi Adam, There are two options. The first is to add an isolation resistor between the output of the amplifier and FET. The second is to use a topology called Riso with dual feedback. Riso with dual feedback will give a more DC accurate solution but...

  RE: ADS8867: Analog ADS8867 16bit SPI IC issue

  Hello Jigar, If you are driving the input of the ADS8867 directly with the INA333, you will need an RC filter and you will be limited to around 10ksps max sample rate to get rated performance. If you want to achieve 100ksps, then I suggest adding an...

  RE: TINA/Spice/OPA314: Spice model for OPA314

  Thanks Tim, that's good to know. Both the OPA313 and OPA316 have been updated recently and are running our latest model architecture, so I'm glad to hear that the results agree in both tools. I'm going to send you a friend request, let's...

  RE: Convergence issue in PSpice with many OPA models

  Etienne, I was able to correct the OPA313 model so it doesn't give a Pspice error. It is in the models folder in the attached project file. The original model was optimized to work in TINA, a free circuit simulator we offer. Apparently TINA is okay...
