  • RE: OPA569: Current monitor output shows non-linearity when output is near positive rail.

    Resolved
    Hi Michael, Hope you had a good weekend as well. The plots on the last post, where the op-amp driving a 25ohm load directly, show the expected behavior. The current sense waveform looks linear until the OPA569 output is right at about +3.285V (~about 15mV…

  • RE: OPA569: Output current seemed stucking at current limit

    Resolved
    Hi Duan, Duan Wu said: I use a DAC to drive it, so just a mouse click, maybe one millisecond. Then your circuit may also suffer from output saturation recovery. Then it makes a difference, whether your circuit starts from output saturation or goes int…

  • OPA569: Generating triangular DC waveform with superimposed 66mV AC sinusoidal noise

    Resolved
    Part Number: OPA569 Hi, This is probably a simple problem. I am trying to generate a DC with superimposed AC noise to do some noise tolerance test. I think, One way the OPA569 can be used as a summing amplifier and feed both AC noise and DC input to generate…

    Hi Gabriel, I am glad the customer was able to find a workable solution for the parallel OPA569 output application. Thanks much to Kai for his assistance along the way. Please close out this e2e inquiry on your end. Regards, Thomas Precision Amplifiers…

  • OPA569: Parallel operation but one is enabled and the other is disabled

    Part Number: OPA569 Hi Team, We have received this inquiry from our customer, Consider a circuit with two OPA569 power amps (Parallel Out pins connected to each other) below, although ENABLE is not shown - if A1 is disabled via ENABLE pin, what would…

  • OPA569: when OPA569 output saturation, OCP function doesn't work

    Part Number: OPA569 Hi expert, My customer find that some OPA569 parts when output saturation, the current limit function doesn't work. The supply voltage is 5.4V, current limit set 600mA. Flag is I_FLAG pin4, DMM Read is Vout pin14/15. As you can…

  • OPA569: NC pin connection

    TI Thinks Resolved
    Part Number: OPA569 Hi, Good day. Our customer wants to know the recommended connection for the NC pin. Do we have a document for this? Please note that this is an aerospace application. Looking forward to your response. Thank you. Regards, Cedrick

  • OPA569: What is the max and typical current draw on the source voltage (ie Pins 12,13)?

    Part Number: OPA569 What is the max and typical current draw on the source voltage (ie Pins 12,13) at V+=5.0V?

  • OPA569: Paralleling OPA569: max number of devices.

    Part Number: OPA569 Hi, Datasheet of OPA569 mentions that multiple devices can be set with a "master" device and slave devices connected through 2 paralleling pins. 1) What is the maximum number of devices that could be set in parallel this…
