  • Recommended SAR ADC input amplifier

    Other Parts Discussed in Thread: MSP430FR2422, TLV376, LM7705, INA240, OPA340, INA293

    Hi -

    My application is for high bandwidth voltage/current measurement of power supplies into an SoC.  I am using an MSP430 to buffer the ADC measurements at ~200 kHz.

  • RE: what can we use instead of TLV3502 for hardware fault detection.

    Dave, 

    TLV3502 is a high-speed comparator and NOT an op amp.  Because comparators are essentially uncompensated op amps, no op amp can match the transition time of a comparator’s output for a given quiescent current, which may be critical in your fault…

  • RE: TINA-TI: Normalize closed loop gain graph

    Well Olaf, I was interested in that parameter stepping and was able to get that to work in TINA V9 for the OPA818 - here I modified that OPA340 example to create figure 1 in the datasheet, V9 file below, the inverting sweep in Figure 2 does not report…

  • RE: OPA320: OPA320

    Hi Attila,

    Often the common-mode and differential input resistance of a CMOS op amp such as the OPA320 aren't listed because they are so extremely high they are of no consequence in a real, functioning op amp circuit. The op amp input resistances are…

  • RE: OPA340: Output waveform question for OPA340

    Hi Mickey,

    Why? Would you explain this and send me a  formula to  calculate Gain?

    This is the issues:

    At DC, the circuit has a gain (10+1)=11 or 20.83 dB (assuming VG1=1)

    When Xc1 = R1, its frequency is 1061Hz or approx. 1kHz. --> this generate a zero in…
