  • OPA625: OPA625

    Resolved
    Part Number: OPA625 Other Parts Discussed in Thread: OPA863 , OPA810 Trying to use the BOM cross tool to match up to the ADA4807-1, it came back with only the OPA625 which looks about right AC wise, but The ADA4807-1 is +/-5V capable, while the OPA625…

  • RE: OPA625: About the output voltage of OPA625

    Hi, the datasheet clearly says that the input voltage must no go below the negative supply voltage. But this would be the case in your circuit, if the input offset voltage results in a voltage at the -input of OPAmp which is slightly negative compared…

    Hi John., The new schematic's simulation result is as I expect. Thanks. Ming

  • OPA625: ADC driver options

    TI Thinks Resolved
    Part Number: OPA625 What would you recommend for this :- I need a new opamp to act as a buffer before entering the ADC we use. Need dual supply +/-5v and able to deal with its input being its rails. (Not able to stop the TIA feeding it from saturating…

  • RE: LMP91000: Differential AD converter input at Vout

    Resolved
    Marco - Here perhaps its best to continue using the LMP91000 and your sensors as normal, while amplifying signal going to ADC. For simplest implementation, an amp like the OPA625 coupled with an ADC like the ADS8860 and oversampling/averaging it or filtering…

  • OPA625: Voltage Reference Buffer

    TI Thinks Resolved
    Part Number: OPA625 Other Parts Discussed in Thread: ADS124S08 , OPA320 , OPA350 , OPA333 Dear Forum Members, I'm writing to you regarding a design problem: We'd like to use the ADS124S08 in one of our products (i.e. sensor signal conversion) and besides…

  • RE: DAC3164: DAC buffer offset

    Hello Nate, I apologize I missed the follow up to this thread. Below is the a proposed design, but due to the lack of the negative reference, you won't be able to go down to -0.5V at the output of the DAC: I mostly used these two references: …
