  • RE: REF6025: SS Pin Connection for Maximum Current

    Hi Luke The short circuit current will be minimum when you short SS pin to GND (or connect 0ohm to GND). It will start increasing as the resistor value between SS and GND increases. Short circuit current will be maximum when you open the SS pin or you…

  • REF6025: CFILT and RFILT questions

    Answer Suggested
    Part Number: REF6025 Hi, three questions regarding REF60xx: 1) Does the yellow marked text refer to CFILT or to CL? (Can the ESR of CFILT really have a noteable impact on the stability as it isn’t a conventional OP/buffer) 2) What is the value of…

  • REF6025: Power Consumption at Vcc =3.3V

    Resolved
    Part Number: REF6025 Team- What would be the power consumption of the REF6025 at Vcc=3.3V? I don't see this number specced in the datasheet and my customer wants to characterize their power usage in a very constrained application. Thanks, Alec

  • RE: ADS1278-EP: Looking for an ADC

    Hi Bryan, Thanks for the reply. Just to confirm, to calculate the capacitor value for the single-ended RC filter based on the differential mode design guidelines as stated in the link you mentioned, I should used C = 1/(2*pi*R*F) instead of C = 1/( 2*pi…

  • RE: ADS1259: Question about power rails, reference voltage vs input signal

    Resolved
    Hi Adam, This should work in theory. As you can see though, in practice there might be additional factors in the circuit that lead to non-ideal behavior e.g. the resistor between the VREF output and ADC input (not sure why it was so large, maybe because…
