  • RE: OPA189: High speed Transimpedance Amp, 10V out

    HI KB, If I understood correctly, the application requires an output voltage of 10V, at 500-kHz, with the TIA configured with the 400Ω gain resistor. The TIA needs to be able to source more than 25mA, and provide high enough slew-rate to support…

  • RE: LM7322: Replacement device recommendation for the LM7322MM/NOPB

    Hello JH, OPA2156 is another potential replacement. Is the "unlimited cap" drive required, that claim is rare.

  • OPA2156: slew rate stability across operating temperature range

    Resolved
    Part Number: OPA2156 Other Parts Discussed in Thread: OPA2677 Hi, do we have any data regarding Slew rate of OPA2156 across its operating temperature range? Can the Slew rate drop from typical 40V/us to as low as 20V/us at high temepratures? Thanks.

  • OPA2156: rising and falling slew rates

    TI Thinks Resolved
    Part Number: OPA2156 Hi Team, It is a regulation of Typ.40V/us of slwe rate. Is there a difference in rising and falling slew rates? If there is a difference in the same conditions, how much is that? Let me know what you think about the conditions described…

  • OPA2156: Question about the input offset voltage specification

    TI Thinks Resolved
    Part Number: OPA2156 In the datasheet of OPA2156, at the begining, the feature section: Low offset voltage: ±25 µV But latter, is shows 25uV is only the typical value, and only for PMOS, the offset of NMOS is more worse than that. I'm not…

  • OPA2156: Multiple opamps in parallel?

    Resolved
    Part Number: OPA2156 Other Parts Discussed in Thread: OPA564 I’m designing a circuit that requires more output current than a single device can deliver - would it be safe to put multiple OPA2156 in parallel to increase the output current?

  • RE: OPA1642: Unexpected behavior in single supply circuit

    Resolved
    Hey Ron, No problem. I will take a look at the previous devices you mentioned for a comparison and try to narrow down some good suggestions for you. What is the intended application that this amplifier will be used for. Will it be used to drive a speaker…
