  • Low temperature characteristics of OPA561

    Resolved
    Other Parts Discussed in Thread: OPA561 , OPA564 We had prototyped the OPA561 as a simple inverting amplifier as attached. But It looks like OPA561 has an oscillation at -10 ℃ or less at our evaluation board. The oscillation began from -10℃ at 1.6MHz…

  • OPA561 / the frequency specification is varied by RCL

    Resolved
    Other Parts Discussed in Thread: OPA561 , TINA-TI Hello, If we change the RCL value, is the AC characteristics (GBW or Phase margine etc..) varied? Our customer faced the output oscillation when they change the RCL value of OPA561. Please see the following…

  • Modified Howland current source (OPA561) with high frequency noise problem

    Other Parts Discussed in Thread: OPA561 I am currently using OPA561 for configuring a high current source(200mA~500mA range), in a modified Howland circuit setting, and is encountering high frequency noise at the output terminal. I just don't know why…

  • OPA561 gets hot when e/s pin is pulled up thru 402k to +12v

    Other Parts Discussed in Thread: OPA561 Hi Mark, Upon review of your reply including the specifications for the maximum voltage to the E/S pin I can see your point. So I then added a 100k ohm resistor from pin 8 (E/S) to ground which forms a voltage…

  • OPA561 gets hot when e/s pin is pulled up thru a 402k resistor to +12V

    Other Parts Discussed in Thread: OPA561 , OPA461 I haved prototyped the OPA561 as a simple inverting amplifier with a negative unity gain. The device is adequately heatsinked. I am operating it with a +12vdc single supply. My input is +5.5vdc which is…

  • OPA561 gets hot when E/S pin is connected thru a 402k resistor to +12v

    Hi Marek, I am definitely connecting +V to +12v and -V to GND (0v) so there should be no confusion on this. I was originally connecting +12v thru a 402k resistor to the E/S pin. In your initial email you advised me that this superceded the +5v maximum…
