  • REF3040: FMEDA Data and MTBF/FIT estimator Data

    TI Thinks Resolved
    Part Number: REF3040 Hi, TI Team. I have found data sources of failure rate namely: 1) www.ti.com/.../estimator.tsp 2) https://www.ti.com/quality/docs/estimator.tsp?OPN=REF3040AIDBZT&CPN=&partNumber=REF3040#resultstable Which number should I…

  • REF3040: Inaccurate voltage reference output

    Part Number: REF3040 Other Parts Discussed in Thread: ADS8332 I refer to the ads8332 datasheet to design the voltage reference circuit, but the final output voltage is 20mV more, and my design voltage is 4.096V，where R239 is 0ohm

  • RE: DDC232: Internal operation of DDC232 32-channel current-to-digital device

    Hello Mark, Please find below the comparison table between the various reference chips. These were some of the parts that we looked at and we have used REF3040 and LM4140 in our higher channel density devices. LM4140 REF3040 REF3140 REF3…

  • LOG114: Problem getting the circuit to work

    TI Thinks Resolved
    Part Number: LOG114 Other Parts Discussed in Thread: REF3040 , I modified the LOG114EVM board to create this circuit: For the first step I didn't connect Vlogout to R5 in order to just evaluate the first amplification step. Unfortunately I cannot…

  • RE: INA213: Recommended INA213 Reference voltage connections

    Resolved
    Gonugunta, When using voltage references the amount of current the REF device can source is important to consider. Since four INA213s will not draw 25mA into the reference pins, there shouldn’t be a problem using the REF3040, and a resistor in series…
