  • ADS8321: Question about VCC / VREF and IN+

    TI Thinks Resolved
    Part Number: ADS8321 Other Parts Discussed in Thread: ADS8320 I have a need for an ADC that can do 3.3V SPI signals, while taking a 0~5V input analog signal. If possible, a device that is P2P with ADS8321 would be great, but I haven't found anything…

  • RE: LTC1865HMS#PBF, LTC1865AHMS#PBF Alternative

    Resolved
    Hi Jake, Take a look at parts like the ADS8320, ADS8321, ADS8325 - all pin compatible, although maybe not 100% software and speed compatible.

  • ADC Peculiar readout - ADS8321

    Resolved
    Other Parts Discussed in Thread: ADS8321 I've been using the ADS8321 a lot lately in prototypes I'm working on for use with strain gauges. I'm using an Analog Devices AD623 to amplify the signal and then into the ADS8321. It's been working perfectly with…

  • ADS8321 Differential input - common mode voltage range vs Vref (fig 3 in datasheet sbas123b)

    Resolved
    Other Parts Discussed in Thread: ADS8321 ADS8321 datasheet figure 3 is unclear. The low limit streches from -0.3V to about 0.95V according to the shadowed area, but the voltage indicated on the right says 1.95V. Which is correct?

  • RE: LOG114: What ADC is suggested to digitize the signal from the LOG114

    Resolved
    Hi Alex, I'm thinking of using the ADS8321 to digitize the output of the LOG114. I have two questions. Can I use the 2.5V reference on the LOG114 to feed the ADS8321? Does the ADS8321 have a daisy chain feature for multiple sensor acquisition? Any comments…

  • RE: LAUNCHXL-F28379D: ADC input signal conditioning

    Resolved
    Hi John, (1) Yeah, I agree; this should have been connected to VREFHI/2. As-is, you will need to ensure that the common-mode of your input signal is within 50mV of VREFHI/2. It should also be possible to remove the two SMT resistors (R60 and R61) and…
