  • OPA363: Capactive Drive limit for OPA363

    TI Thinks Resolved
    Part Number: OPA363 Hi, I would like to know if the OPA363 will be able to drive a 50nF load? If it can drive it, what is the maximum capacitive load that it can drive? If no, are their any alternate, high current/capacitance drive opamps that we can use…

  • OPA363: difference in part numbers

    Resolved
    Part Number: OPA363 What is the difference between the OPA363AIDBV and the OPA363IDBV other than cost? There is nothing in the data sheet that tells me what the "A" in the part number refers to.

  • RE: DAC43701: Cannot generate a constant audible signal

    Hi Napoleon, Thanks for your schematic. Have you been able to measure the square wave output on the output of the OPA363? It looks like the voltage output from the DAC might not be high enough to enable the OPA363 via the enable pin. The OPA363 datasheet…

  • OPA380: Photodiode Current-to-voltage conversion

    Resolved
    Part Number: OPA380 Other Parts Discussed in Thread: OPA363 , OPA365 , OPA810 , TLV9002 , OPA376 , ADS1115 Hello, I have two questions. I plan on using the OPA380 as a current-to-voltage converter for a thesis project. The current source is a photodiode that…

  • RE: OPA341: if shut down for an extended period, does not return.

    Resolved
    Ken, OPA363 is a good replacement for OPA341 in most applications.

  • PGA112: Measuring single-ended values close to GND

    TI Thinks Resolved
    Part Number: PGA112 Other Parts Discussed in Thread: REF3230 , OPA2364 , TINA-TI , OPA364 , OPA363 I am intending to use the PGA112 amplifier to measure voltages with a wide dynamic range. Peak voltage to be measured is 60 V, scaled to < 3V with a 100k /…

  • RE: OPA2180: Large offset in inverting buffer circuit that is outside the expected 70uV spec for the device

    Resolved
    Hi Ross, I believe you forgot to upload your schematic, but there are many other sources of offset that you are not considering, such as that produced by bias current flowing through large impedances, CMRR, PSRR, etc. You may find this article useful…

  • RE: Transimpedance amplifier with LMH6629 problem with irrational bias current

    Resolved
    Hello Emmanuel, I wonder if you have a potential instability because of the time-constants involved and the OPA363 servo-amp is unable to get to a stable voltage on start-up. One thought I have is to have a 1K resistor to ground on the non-inverting…

  • RE: Opamp Selection - Output leakage current < 1nA, Shutdown, RR

    Ben, Shutdown current of OPA357 for Vs=3.3V is around 250nA at 50C (see graph below). Since you only specified RR swing requirement but no speed, I would suggest you to take a look at OPA341 (see graph below) as well as OPA363, OPA373 and OPA322. …
