  • OPA330: Part Markings (Bottom)

    Resolved
    Part Number: OPA330 I would like help identifying the marking 23W9 found on the bottom of part OPA330AIDCKR. I am under the assumption this is not the Date Code based on the labeling of the package and reel which states the d/c is 2211. Thank You.

  • RE: OPA330: Output voltage equal to supply and not input

    Hi Clément, We are planning to do that once we are done with our board validation in order to investigate further. Please let us know when you are able to removed one of the non-functioning OPA330 from PCB, and characterized it to see if the part…

  • OPA330: OPA330AIYFFR

    TI Thinks Resolved
    Part Number: OPA330 This part is configured as a buffer using OPA330AIYFFR. When 0.5V is applied to the input I measure 2.2V, the correct value should be close to 0.5V. Please help to verify if there is an issue with the part.

  • OPA330: Input Impedance

    Resolved
    Part Number: OPA330 I am having a little difficulty understanding the impedance specifications. The data sheet for the OPA330 does not list any impedance values. I did read a post in E2E that explained that you could calculate the common-mode impedance…

  • RE: OPA4330: A rectifier circuit is built with op amps and diodes, and the waveform after rectification and filtering has a lot of ripples.

    Resolved
    Kevin, First, OPA330 maximum supply voltage is specified at 5.5V BUT you seem to use +/-5V - that is a total of 10V! If you have done this, the part is most likely damaged. You may use max single supply +5.5V or max dual supply +/-2.75V but not +/-5V…
