    TI Thinks Resolved
    Part Number: OPA3S328 Other Parts Discussed in Thread: TMUX1308 Hi team, Why ton/toff of OPA3S328`s internal switch is so slow: It need 1~2 uS, but for general MUX device, even low cost one, like TMUX1308, it only need tens of nS for ton/toff: So I am…

  • RE: Recommended ADC + Transimpedance-Amplifier and schematic to measure nanoamps currents

    Michael Hartshorne

    Hello Javier, From the Precision Amplifier team, we have several devices that can be used as a TIA. I'll assume at the moment you have a low voltage, isolated, floating supply, for which I will recommend a few low-voltage amplifiers that can work well…

    HI User, The ADC timing requirements are clear on the post above, however, I require clarification on the maximum delay that can be afforded for mux settling. We can certainly provide you a few circuit suggestions if you clearly define the settling requirements…

  • RE: an opamp which has high input bandwidth

    SimaJalaleddine
    SimaJalaleddine
    Hello Yuki, Usually gas sensors are much lower than <50MHz of bandwidth due to the slow rise times. Also, that is a wide range of current, I would suggest an amplifier with internal gain switches for this application. OPA3S328: 40MHz App note on…

    HI Jeremy, Please see below the OPA3S328 configured on a programmable gain amplifier configuration. The OPA3S328 input impedance is high since it is intended for transimpedance amplifier applications (but not as high as the ultra low leakage LMP7721 or…

    Resolved
    Hi Ahmet, Thanks for choosing ADS8699 in your design. Please see my feedback below: Schematic: 1. Firstly, ADR5045 is a 5V voltage reference, the ADS8699 requires 4.096V reference voltage, so the ADR5045 can not be used for this ADS8699. Also, the internal…
