Part Number: TLV2781 Other Parts Discussed in Thread: TLV9061 , TSV911 dear
could you help to offer TLV2781IDBVER ESD HBM and CDM data which can not find in DS,thanks in advance~
Other Parts Discussed in Thread: TLV2781 Hi sir, Currently my customer use HT9291 design schematic. Survey TI's OP, I think TLV2781 can replace. May I know the circuit can implement application?
Other Parts Discussed in Thread: TLV2781 , OPA350 , OPA365 , OPA355 Hi everyone:
I want to design a voltage amplifier. I'm using the low consumption TLV2781 and a single supply op-amp desing found in page 6 ofthe following file:

Hello Brian, because the DRV8301 has only two CSA and I wanted to use three identical CSA and I’m not sure but I read somewhere that external current sensing may be more accurate. Sorry for the confusion, I meant the TLV2781 and TLV9061! I’ve found some…
James,
The TLV2780 is one member of a product family that includes the TLV2781 and TLV2782, which have Pspice models in their product folders.
Would those models work for your application?
Regards, John
Thanks for the suggestions. While looking through the layout we found one small error in our design that might relate to this. In making this layout more compact we changed the TLV2781 into a package with 4 opamps, TLV2784. Leaving one opamp unconnected…
Hi Chris,
Um, so would that imply that the offset voltages are on the order of 0.052/700 = 74µV for the current sensors and 0.023/80 = 287µV for the voltage sensors?
That is far lower than I had anticipated; I'm using a TLV2781 op-amp for the current…
Hi Sean,
I think you made an error in your current gain calculation for the DRV8301_69M-KIT. The board does not use the op-amps inside of the DRV-8301. If you look at the schematic which is part of the MotorWare package, you will see that external circuits…
Hi Yanming,
I've attached the schematic.
I cut power to the inverter and bridge, but still get the same results.
I'm using a benchtop power supply for 5V, since I suspected the 7805 was shutting down.
But I still see the same thing at the program…
