  • RE: OPA1632: input voltage noise test instrument

    Hi Roy, Attached is a PowerPoint presentation that outlines our noise measurement process. Take special attention to slide 18. OpAmpNoiseAnalysis.ppt As an example, attached here is a TINA-TI example simulation with the OPA657 as the DUT. The LMH6629…

  • OPA1632: Modulation of differential output using OPA1632D

    TI Thinks Resolved
    Part Number: OPA1632 Hello, I'm using a MCU to generate a sine-wave (as single ended signal) that is amplified and changed to differential signal with a OPA1632D. The enable pin of the OPA1632D is used as a modulation input pin. The circuit works…
