  • OPA990: About DRL package

    Resolved
    Part Number: OPA990 Dear, Support Team. The OPA990 data sheet says "DRL package is preview only". Will it be released? If so, when will it be scheduled? Best Regards, Mariko Okutsu

  • OPA990: IS anyone reporting problems with this part, OPA990S in SOT23-6?

    Resolved
    Part Number: OPA990 Other Parts Discussed in Thread: OPA170 , It seems as if the pinout may be wrong. Our input to the + on pin 1 is being crushed (to 0V) when we enable the Op Amp (/SHDN goes low, which should be off, but their naming is wrong and low…

  • OPA990: Pin Assignment Discrepancies

    Resolved
    Part Number: OPA990 Other Parts Discussed in Thread: TLV9101 , Hi Team, Our customer noticed that the pin assignments and drawings of the OPA990 and TLV9101 SOT-23 6-pin package were not properly matched on the datasheet. They've experienced an issue designing…

  • RE: TLV1822-Q1: TLV1822QDRQ1

    Hi Shivaraj, As Clemens said, it's possible that you've damaged the device. The OPA990 output (TLV1822-Q1 input) can swing negative such that it goes beyond the absolute maximum ratings of the device.

  • RE: LM2904V: High Side Current Sense Output Issue

    Resolved
    The LM2904V does not have rail-to-rail inputs; the input common-mode voltage range ends 2 V below the positive supply. Use something like the TL081H or OPA990. To be able to use input voltages above the supply, you need a specialized current-sense amplifier…

  • OPA990: TI P-P solution to replace NCS21911 SOT-5P

    Resolved
    Part Number: OPA990 Other Parts Discussed in Thread: OPA991 Hi sir, Please kindly recommend TI P-P solution to replace NCS21911 SOT-5P. Other spec requirement is: Offset: 25uV-800uV VCC: +36V (at least >16V) Thanks a lot! BR, Sean Liao

  • RE: OPA170: Designing with OPA170.

    Resolved
    Hi Sv, No problem! As long as you choose the proper external resistors for your difference amplifier, then I think this would work. Also, why did you choose the OPA170? We have the OPA990, which is our next generation of high voltage op amps that offer…

  • RE: OPA593: OPA593 Output query

    Hi Tejendra, OPA990 is the rail to rail op amp, but it is unable to source beyond ±40mA-50mA current range. What are the application's current requirements? Best, Raymond

  • RE: OPA170: Designing with OPA170

    Hi SV, Lots of great questions: The maximum current can be changed depending on the type of MOSFET you use and the voltage you apply to the gate. It's not very obvious but this covered by the Isolation Resistor Stability Video in the Precision Lab…
