  • OPA817: OPA817

    Resolved
    Part Number: OPA817 Tool/software: Hi, I have read the answers and looked at the datasheet, but I still have questions about the PD pin in the opa817. I see Table 7.5 and understand that I need to apply 5V to the PD pin to enable the op-amp. However,…

  • OPA817: OPA817 settling time

    TI Thinks Resolved
    Part Number: OPA817 Tool/software: Hi all, Recently, I am very confused about the settling time measurement of operational amplifier. Before measuring the settling time of OPA817, I do a simulation in TINA, and the settling time of OPA817 is about…

  • OPA817: Power Down mode

    Resolved
    Part Number: OPA817 Tool/software: Hello there, I was going through the datasheet of OPA817. In page number 3, it is shown in the table, to disable the amplifier PD pin must be pulled high. But in page number 21, in the layout recommendation, PD pin…

  • OPA817: Slew Rate not keeping up with input

    Part Number: OPA817 Tool/software: To Whom it may concern: I am using an OPA 817 in the voltage follower configuration with a o 0 ohm in the feedback path (connecting pin 2 to pin 3). I have a 76.8 MHz 1Vpp square wave on the non-inverting input and…

  • OPA817: Optimized feedback and gain resistors for gain = 1.1 and gain = 3.3

    Resolved
    Part Number: OPA817 Other Parts Discussed in Thread: THS4541 , OPA837 Tool/software: Hello TI experts, my design includes two OPA817 with a gain of 1.1 and 3.3. Are there some recommandation from TI for the "best" feedback resistor values in case of…

  • RE: OPA818: Parallel an OPA818 (7 V/V stable) & an OPA817 (unity stable) in an alternative Power-Down scheme

    Hi Alec, Thanks for the detail explanation. I am abandoning the parallel OPA817||OPA818 outputs w/ PD design for now, as I realized that there's an extreme scenario where as much as +/- 6.3 Vpeak may be present to the output of OPA817||OPA818 outputs…

  • OPA817: Drift of bias current

    TI Thinks Resolved
    Part Number: OPA817 Hi experts, Could you please tell me the bias current drift (Vs=±5V) of OPA817DTKR? The bias current of the FET input op amp grows exponentially with temperature, so I'm concerned about its drift. Is it possible for you to…

  • RE: BUF802: DC to 100MHz Frequency Response

    Resolved
    Hi Ignacio and Saket, Thanks for your kind reply, I think in my case it is hard to calibrate the front-end digitally to get 0dB gain. Anyway, it seems that OPA659, OPA814 and OPA817 can meet my requirements. Thanks for your support. BR, Chi-Yuan
