  • RE: OPA567: OPA567 as non inverted LED driver

    Hi Raymond, thanks for your answer. Please excuse my late response to your reply. The PWM input is set for a required LED current (LED -- LA W57B) and then is not changed for a longer time. This is a quasi static input voltage at the OPA567. Should phase…

  • OPA567: Performance with large load capacitance

    Resolved
    Part Number: OPA567 Hi, Im planning on using the OPA567 in a battery simulator circuit. One concern I had is how the circuit behaves with large load capacitances (1mF bulk cap). I simulated it in TINA and the stability looked okay (1ohm Riso), but wanted…

  • OPA567: what voltage should we expect on Iset pin (pin6)

    Resolved
    Part Number: OPA567 Hi, I tried to make my IFLAG high after EN is high with Vin and Vset are both 2.5V but failed. I was checking any potential cause and I found my Iset pin (pin6) is always 0V. I thought I will measure a +1.18V. Will there really be…

  • RE: OPA569: Is there a similar OP with OPA569 ,but more smaller size or smaller current?

    Resolved
    What are you requirements (supply and signal voltages, frequencies, offset voltage)? Some similar devices might be TLV4112 or OPA567.
