  • OPA170: Increasing opamp gain

    TI Thinks Resolved
    Part Number: OPA170 Other Parts Discussed in Thread: TLV9101 , OPA990 , TL081H Hi, this is my new thread in relation of my other thread ( OPA170 Abnormal Behaviour ). My setup (use as current sensor : V2 connecting V3 with ~0.1 ohm;150C test) V1 = 12V, V3…

  • OPA703: Need ESD Data for OPA703AN

    TI Thinks Resolved
    Part Number: OPA703 Other Parts Discussed in Thread: OPA990 Looking for ESD level data on the OPA703NA/250 and /3K devices. Quality report refers to the data sheet… data sheet has no information. Thanks!

  • LM321: Op Amp alternative Help Needed

    Answer Suggested
    Part Number: LM321 Other Parts Discussed in Thread: LMV321-N , , LMV321 , TLV9001 , TS321 , , OPA990 , OPA170 Hi All I have having difficulty locating a supplier for the LM321MF SOT-23 Is there a newer alternative component available with the same package? …

  • RE: Is that possible to add a current amplifier on the 3.3V build-in LDO of DRV8340H?

    Yes; the DVDD pin of the DRV8340-Q1 can be used as a voltage reference (although it cannot sink much current). It would be possible to configure a strong opamp (e.g., OPA990, OPA551) as a voltage follower. But just adding a separate LDO (e.g., LP2950…

  • RE: TLV9051: Alternate P/N required - TLV9051IDBVR

    I was asking because the TLV9051 is faster than the cheaper and more common TLV9001. Anyway: TLV9041, TLV9061, TLV9101, TLV9151, OPA990

  • RE: OPA991: OPA991 is not meeting its slew rate specification.

    Hi Lidong, If a 1.5V/us slew rate is all that is needed then the OPA990 should work. However, please understand that there is a difference between small signal and large signal. Small signal rise times are dependent on the bandwidth of the device. Since…

  • RE: OpAmp replacement suggestion

    Resolved
    Hi David, For the LM324, TI also offers an LM324. But it is not a newer upgraded device. If you can use two dual channel devices instead of one quad channel, I would recommend taking a look at the LM358B. For the MC3317, a newer device TI has is the OPA990…

  • RE: Replacement for LM107

    Resolved
    The LM107 regulates the upper LM338 so that the current through the two 0.1 Ω resistors is the same. This circuit can use any high-voltage opamp whose input common-mode range includes the positive rail. This is not true for the LM741, but the OPA990…

  • RE: LMV321: Output leakage voltage

    Resolved
    Makoto-san, OPA990 is another part that I remember starting low during power up. Be sure to test that it work to your satisfaction.
