  • REF2041: hi-Z output when disabled

    TI Thinks Resolved
    Part Number: REF2041 Tool/software: Hi, We are using REF2041 to provide the reference voltage to AD5686R-EP . Since AD5686R has internal Vref enabled by default, we keep REF2041 EN=LOW (disabled) until we turn off AD5686R's internal Vref. According…

  • REF2041: back-driving output pin momentarily

    TI Thinks Resolved
    Part Number: REF2041 We are using REF2041 to supply an external reference to AD5686R-EP . During power up, AD5686R-EP will get powered up first (i.e. before REF2041 is up) and its Vref pin will default output a 2.5V, meaning REF2041 Vref pin will see…

  • REF2041: turn on/off time

    TI Thinks Resolved
    Part Number: REF2041 Hi, REF2041 datasheet provides a turn on time of 500us. (1) 500us is referring to the rise time to reach 99.9% with Cload=1uF, correct? (2) is there a propagation delay between EN and Vref/Vbias? Or if the 500us already included…

  • ADS1220: Output Data Format

    Resolved
    Part Number: ADS1220 Other Parts Discussed in Thread: INA823 , REF2041 Section 8.5.2 of the data sheet describes the data output format as twos compliment but shows a +/-FS example that would be appropriate for a differential input setup where 0 is mid…

  • REF3440: Extension of current capability by using a parallel resistor

    Resolved
    Part Number: REF3440 Other Parts Discussed in Thread: REF2041 , , ADC128S052-Q1 As stated in the datasheet, the REF3440-Q1 can deliver 10 mA at 4.096 V output. In my application, I need some mA additional current. As the REF3440-Q1 can also sink 10…

  • ADS1220: Measuring AC peak in HV induction

    TI Thinks Resolved
    Part Number: ADS1220 Other Parts Discussed in Thread: REF2041 , We are measuring an induced AC voltage (50/60Hz) that can range from 100mV PP to 150V. Isolation would be nice but that can come later. We were looking at a peak detector with AC coupling…

  • RE: Not sure how to find VCC/2 supply chips

    Resolved
    Hi Lloyd, Can you provide any information on how you'll be using the supply voltage? This might help us find the device you are looking for. The only device I know of that outputs a supply and 1/2 of the supply is the REF2025, REF2030, REF2033, and…
