  • TLV521: high-side current sensing

    TI Thinks Resolved
    Part Number: TLV521 Dears, Just curious what's the purpose for adding a transistor in the sensing circuit? Generally, without the transistor, just use an op-amps could monitor the current. Hugh

  • RE: TLV521: TLV521

    Hi both, yes, such a statistical approach may be reasonable for many cases. But for a professional product you will need maximum specifications. We sell a product with a board containing more than 30 OPAmps (all from TI by the way ). If only one OPAmp…

  • TLV521: High precision current sense op amp for measuring 1uA current

    Part Number: TLV521 Other Parts Discussed in Thread: OPA355 , THS4631 Hi Team, I would like to get your suggestion for the customer request below as I am lacking in seeing the slew rate information in other datasheet for the complete requirement of our customer…

  • TLV521: What value of isolation resistor should be used

    TI Thinks Resolved
    Part Number: TLV521 Team, customer plans to use TLV521 op amp in thier design as a buffer for a voltage reference. As such, they plan to use it as unity gain follower with a 10μF filter capacitor. Their question is: What value of isolation resistor I…

  • TLV521: Clipping of waveform with Low & high pass filter

    Resolved
    Part Number: TLV521 Have attached a ckt, basically its a low pass filter of 240Hz & then high pass filter of 10Hz. Can someone tell why output of HFP filter is getting clipped. Is it due to capacitive load? If yes how to solve it? Otherwise CMR range…
