  • High gain ac simulation OPA349

    Resolved
    Other Parts Discussed in Thread: OPA349 I have ac simulation of OPA349 in inverting configuration that has large feedback resistor (<10K). With very large gains, the simulation shows a drastic drop in low freq gain (> 1M no gain at all). Does anyone…

  • RE: LPV811: Higher bandwith part similar to LPV811

    Carlos, You do not specify what other parameters besides IQ and bandwidth are critical in your customer's application but here are some other options: OPA369 (800nA, 12kHz) , OPA349 (1uA, 70kHz) and OPA379 (2.9uA, 90kHz).

  • RE: LM358: A intergrator of LM358

    Thank for your repply. Today I used OPA349 instead. And the wave shape in scope like this: channel 1 : power supply which is 6V DC channel2 : output voltage which have been intergrated

  • sn105125: What is the total unloaded power consumption?

    TI Thinks Resolved
    Part Number: SN105125 Other Parts Discussed in Thread: TLV741P , TLV733P , OPA349 , LP5907 , TPS709 , TPS706 I need a good low power voltage reference for an analog circuit that should be quiet but doesn't have to be ultra-precise. The SN105125 seems like…

  • INA333 Gain Calculation

    Other Parts Discussed in Thread: INA333 , OPA349 TI Team, The gain calculation shown on page 14 of the datasheet--an application circuit--shows that the INA333 has a gain of 10. I'm assuming that this value is derived from the RLD drive circuit, in series…
