  OPA313: Interaction between OPA313 and OPA316 pspice models

  TI Thinks Resolved

  Part Number: OPA313 Current issue is that I am comparing some circuits using OPA313, OPA314, and OPA316 pspice models. If I simulate identical circuits using OPA313 and OPA314 in the same schematic, I get results as I would expect. As soon as I add an...

  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: TI closet solution with Rohm_BU7445HFV

  Hello Shotaro-san, Here is a list of devices that might be of interest to the customer. The only issue is that the TLV9041 (see TLV9042 page on ti.com) will probably not RTM for a while yet. ► Part Number TLV9041 TLV313 OPA313 OPA348...

  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: OPA2333A-EP: CA3420 Replacement

  Ambroise. The closest to CA3420 would be OPA196 with min +/-2.25V supplies or OPA170 with min +/-1.35V supplies. But if you must operate on +/-1V supplies, you may consider OPA317 or OPA313.

  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...
